-Synuclein interacts indirectly with Elk-1 via ERK, and prominently attenuates Elk-1 phosphorylation on Serine 383 along with c-Fos induction in response to EGF in Neuro2A cells (Iwata et al., 2001). Sweet taste receptor signaling network: possible implication for cognitive functioning. No deficits in the immunological response were found in these mice. Elk-1 is activated through phosphorylation by the three classes of MAP kinases, ERK, JNK, and p38 (Cavigelli et al., 1995; Gille et al., 1995; Whitmarsh et al., 1995; Enslen et al., 1998; Cruzalegui et al., 1999). (2004). They showed that overexpression of Elk-1 in primary neurons decreases cell viability, whereas Elk-1 siRNA-mediated knockdown increases cell survival. Schwarze S. R., Ho A., Vocero-Akbani A., Dowdy S. F. (1999). Two-thirds are expressed in most adult tissues, albeit with different levels of expression (Hollenhorst et al., 2004). When mutated on this residue, Elk-1 overexpression in the cytoplasm is not toxic anymore in cultured hippocampal neurons. Nuutinen S., Barik J., Jones I. W., Wonnacott S. (2007). (2001). Cocaine induction of ERK proteins in dorsal striatum of Fischer rats. Elk-1 is restricted to the nucleus in non-neuronal cells (Janknecht et al., 1994; Pingoud et al., 1994), a result expected for a transcription factor, but expressed in both cytoplasmic and neuritic compartments in addition to the nucleus in mature neurons (Sgambato et al., 1998a; Vanhoutte et al., 2001). This, in turn, results in an increased binding to SRF via the B box, and overall increased DNA binding of Elk-1 to the 5CAGGA motif of the SRE. Genome-wide analyses reveal properties of redundant and specific promoter occupancy within the ETS gene family. Future research will reveal the exact role of Elk1 in the pathophysiology of depression.

G., Wasylyk B. Elk1 may be a downstream target of BRCA1 in its growth control pathway. Guaranteed product quality, expert customer support. The striatum is a structure central to reward and habitual behavior and neurobiological changes in this region are thought to underlie the pathophysiology of addiction disorders. Mitogen- and stress-activated protein kinase-1 deficiency is involved in expanded-huntingtin-induced transcriptional dysregulation and striatal death. It is a member of the ternary complex factor (TCF) subgroup of the Ets protein family, along with Sap1 and NET/ERP/SAP2/Elk-3. This retrograde trafficking induced by glutamate involves a recruitment of activated ERK and Elk-1 to macromolecular complexes comprising markers of clathrin-dependent endocytosis, originating, at least in part, from the endocytosis of -amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors (Trifilieff et al., 2009). Local inhibition of ERK blocks the expression these behaviors. ERP, a new member of the ets transcription factor/oncoprotein family: cloning, characterization, and differential expression during B-lymphocyte development. Kasza A., O'Donnell A., Gascoigne K., Zeef L. A., Hayes A., Sharrocks A. D. (2005). Epub 2021 Jun 12. Shaw P. E., Schroter H., Nordheim A. Boros J., Donaldson I. J., O'Donnell A., Odrowaz Z. Another challenging issue regarding Elk-1 functions within the brain is to further investigate the other post-translational modifications described so far in non-neuronal cells, including SUMOylation and ubiquitination. Vanhoutte P., Nissen J. L., Brugg B., Gaspera B. D., Besson M. J., Hipskind R. A., Caboche J. Molecular phylogeny of the ETS gene family. MOR signaling networks and the MAPK pathway are dysregulated in human heroin abusers, Figure 2. Jacobs D., Glossip D., Xing H., Muslin A. J., Kornfeld K. (1999). Elk1 is a transcription factor that is activated by all three MAPK pathways. You may switch to Article in classic view. Similar results were obtained in the visual cortex, where Elk-1 is transiently phosphorylated by a visual stimulation applied after a period of dark rearing (Kaminska et al., 1999). Elk-1 is an alternative splicing variant lacking the SRF interaction domain and a part of the Elk-1 DBD (Rao and Reddy, 1993). The ePub format is best viewed in the iBooks reader. The .gov means its official. Genome-wide analysis reveals PADI4 cooperates with Elk-1 to activate c-Fos expression in breast cancer cells. Official gene symbol, which is typically a short form of the gene name, according to HGNC. Hollenhorst P. C., Shah A. Valjent E., Pages C., Rogard M., Besson M. J., Maldonado R., Caboche J.

Bethesda, MD 20894, Web Policies Their recruitment in vitro correlates with Elk-1 binding to activated ERK via its DEJL domain. All Other Species; However, given the transient phosphorylation of Elk-1 in response to mitogenic stimuli, one can speculate that kinase activity precedes phosphatase-mediated effects on Serine 383 phosphorylation state. These results are provided for demonstration purposes only. the display of certain parts of an article in other eReaders. Cell Cycle. Given the key role of Elk-1 in the recruitment of MSK-1 at the vicinity of histone H3 (Zhang et al., 2008), it would be interesting to analyze a possible synergy between Elk-1 and MSK-1 in neuronal protection in HD. This interaction enhances BRCA1-mediated growth suppression in breast cancer cells. Reduced activation and expression of ERK1/2 MAP kinase in the post-mortem brain of depressed suicide subjects. Ligeza A., Wawrzczak-Bargiela A., Kaminska D., Korostynski M., Przewlocki R. (2008). Li Q. J., Yang S. H., Maeda Y., Sladek F. M., Sharrocks A. D., Martins-Green M. (2003). Elk-1 contains three potential SUMOylation sites, the Lysines 230, 249, and 254 lying within the R motif. The R domain is crucial for the repression of Elk-1 transcriptional activity. ERK-induced Elk-1 phosphorylation is also detectable in hippocampal neurons after induction of long-term potentiation (LTP; Davis et al., 2000) or during contextual fear conditioning (Sananbenesi et al., 2002). This is an open-access article subject to an exclusive license agreement between the authors and Frontiers Media SA, which permits unrestricted use, distribution, and reproduction in any medium, provided the original authors and source are credited. MSK2 and MSK1 mediate the mitogen- and stress-induced phosphorylation of histone H3 and HMG-14. [6] In post-mitotic neurons, a variant of Elk1, sElk1, is expressed solely in the nucleus because it lacks the NES site present in the full-length protein. In these mice, the induction by cocaine of c-Fos and Dyn but not Zif268 expression is altered (Brami-Cherrier et al., 2005). The DEF (or FXFP) domain is more specific since it is only required for the binding of Elk-1 to activated ERK. Sumoylation represses transcriptional activator activity as it results in recruitment of HDAC2 to target gene promoters which leads to decreased histone acetylation and reduced transactivator activity. Diagram illustrating functional domains and major post-translational modifications of the Elk-1 protein. In order to elucidate the role of Elk-1 interaction with DNA, decoy oligonucleotides were used to block either Elk-1 or SRF binding to DNA. While the ERK cascade is activated by growth factors and mitogens, the JNK and p38 cascades respond to cytokines and stress. Kim JH, Choi DS, Lee OH, Oh SH, Lippman SM, Lee HY. These mice also have age-dependent changes in ERK activation. 2015 Mar 13;40(5):1091-100. doi: 10.1038/npp.2014.286. Contents 1 Structure 2 Expression 3 Splice variants 4 Signaling 5 Clinical significance 5.1 Long-term memory 5.2 Drug addiction 5.3 Pathophysiology 6 References 7 External links The role of these pathways in the glucose-induced proliferation of islet beta-cells can now be assessed. In fact, sElk1 counteracts Elk1 in neuronal differentiation and the regulation of nerve growth factor/ERK signaling. Although genetically redundant, ELK1 was obligatory for AR-dependent growth and clonogenic survival in both hormone-dependent PC and castration-recurrent PC cells but not for AR-negative cell growth. The transcription factor Elk-1 is downstream of ERK, and its activity, regulated by ERK-dependent phosphorylation, leads to transcriptional activation of target genes ( Davis, Vanhoutte, Pags, Caboche, & Laroche, 2000 ). Another post-translational modification is the conjugation to SUMO (Small Ubiquitin-like MOdifier), which relocalizes Elk-1 in the cytoplasm. Its promoter is regulated rapidly and transiently by mitogens via the SRE (Treisman et al., 1992), which binds the ternary complex formed by two molecules of SRF and one of the TCFs (Hill et al., 1993). Silencing of Elk1 activity has also been found to decrease cellular responses to withdrawal signals and lingering treatment of opioids, one of the world's oldest known drugs. Elk-1 interacts with neuronal microtubules and relocalizes to the nucleus upon phosphorylation. Background: The binding of Elk1 to SRF happens due to protein-protein interaction between the B domain of Elk1 and SRF and the protein-DNA interaction via the A domain.[6]. Phosphorylation by MAP kinases can occur on at least nine residues in the C domain of Elk-1 (Cruzalegui et al., 1999), two of them, Serine 383 and Serine 389, being crucial for the transcriptional activity of Elk-1. 2017 Apr 1;81(7):585-594. doi: 10.1016/j.biopsych.2016.09.015. Unraveling the spatio-temporal regulation of Elk-1 downstream of ERK may give further insights into the role of this signaling module in neuronal plasticity, memory formation, and drug addiction, but also in neuronal survival in neurodegenerative processes. In conclusion, Elk-1 phosphorylation plays a dual role in gene regulations, by promoting chromatin remodeling through histone acetylation and phosphorylation, and via the recruitment of coactivators of the basal transcriptional machinery. Activation of ternary complex factor Elk-1 by MAP kinases, MAP kinase-dependent transcriptional coactivation by Elk-1 and its cofactor CBP. (2000). Conversely, SUMOylation of lysine residues lying within the R domain of Elk-1 also prompts the export of Elk-1 from the nucleus toward the cytoplasm (Salinas et al., 2004). One-trial avoidance learning is also associated with a specific increase in the phosphorylation of ERK, Elk-1, CREB, and c-Fos expression in the hippocampus (Cammarota et al., 2000). The C (or transactivation) domain contains the amino acids that are phosphorylated by MAP kinases. This site needs JavaScript to work properly. 1998-2022 Abcam plc. Elk1 Transcription Factor Activity Assay from Assay Genie. The B domain allows Elk1 to bind to a dimer of its cofactor, serum response factor (SRF). In this model system, ERKs activation is involved in the induction of zif268, c-fos, and mkp-1 (MAP kinase phosphatase 1). Diabetes. The calcium/calmodulin-dependent protein phosphatase calcineurin is the major Elk-1 phosphatase. Blood. Two variants of Elk-1 have been described so far, Elk-1 and sElk-1. In a further study, local microinjection of pharmacological antagonists revealed that taste-induced Elk-1 activation in the IC depends on glutamatergic, dopaminergic, and acetylcholinergic receptors stimulation (Berman, 2003). Elk1 also inhibits transcription of presenilin 1 (PS1), which encodes a protein that is necessary for the last step of the sequential proteolytic processing of amyloid precursor protein (APP). (1998) showed that aversive taste-learning experience-induced transient phosphorylation of ERK, JNK, and Elk-1 (but not p38 nor AKT) in the insular cortex (IC). Integrating these data, we identified the Elk-1 transcription factor as a candidate regulator of prodromal changes in HD. Frequent redundant occupancy was detected that correlated with housekeeping classes of genes, whereas specific binding examples represented more specialized genes. (2000). Decreased Erk-mediated Elk1 phosphorylation is observed in the hippocampus and prefrontal cortex of post-mortem brains of suicidal individuals. In vivo, zif268 mRNAs are induced within the dentate gyrus (DG) immediately after a high frequency tetanus of the perforant path. Lindecke A., Korte M., Zagrebelsky M., Horejschi V., Elvers M., Widera D., Prullage M., Pfeiffer J., Kaltschmidt B., Kaltschmidt C. (2006). Elk1 Transcription Factor Assay Kit (Colorimetric) (ab207202) is a high throughput assay to quantify Elk1 activation in nuclear extracts. Serum- and glucocorticoid-inducible kinase 1 enhances zif268 expression through the mediation of SRF and CREB1 associated with spatial memory formation. If one of these ingredients, such as SRF, is missing, then a different output occurs. 21d. Specific and differential activation of mitogen-activated protein kinase cascades by unfamiliar taste in the insular cortex of the behaving rat. The D domain plays the key role of binding to active Mitogen-activated protein kinases (MAPKs). . Pastorcic and Das (2003) defined Elk-1 as a potent repressor of transcription of the presenilin 1 gene (PS1) encoding for a protein required for the final step of the sequential proteolytic processing of amyloid precursor protein (APP), which produces highly amyloidogenic variants of A (A42/43 polypeptide). Cammarota M., Bevilaqua L. R., Ardenghi P., Paratcha G., Levi de Stein M., Izquierdo I., Medina J. H. (2000). The ERK pathway is also critical for the retrieval (or expression) of a previously established CPP, in the absence of drug administration. Mitogen-induced recruitment of ERK and MSK to SRE promoter complexes by ternary complex factor Elk-1. Publishing research using ab207202? Conclusions: (2007). As illustrated in this section, Elk-1 phosphorylation has been shown to be modulated in various CNS diseases. ELK1. MEK inhibitors block Elk1 phosphorylation and, thus, impair acquired conditioned taste aversion. Another residue, Threonine 417 is phosphorylated in neuronal cells by a still unknown kinase. Activation of the ERK pathway, and specifically phosphorylation of Elk-1 at Serine 383, in vivo or in vitro, evokes an enhanced binding of the mSin3AHDAC complex, and hence histone deacetylation and chromatin compaction. This is because activation of Elk1 can trigger other molecular events that do not require Elk1 to bind DNA. We examined molecular mechanisms related to MOR in postmortem human brain striatal specimens from a homogenous European Caucasian population of heroin abusers and control subjects and in an animal model of heroin self-administration. This PIASx-mediated coactivation of Elk-1 depends on the binding of PIASx to Elk-1, independently of the E3 activity of PIASx (Yang and Sharrocks, 2005). Functional dissection of the transcription factor Elk-1. The N-terminal Ets-DNA binding domain recognizes GGAA/T sequences. 8600 Rockville Pike already built in. Located adjacent to the B domain, the R domain is involved in suppressing Elk1 transcriptional activity. Histone H3 and MSK-1 phosphorylation, along with transcriptional dysregulations, may account for striatal degeneration in R6/2 mice. This expansion causes protein aggregation, transcriptional dysregulations, neuronal dysfunction, and finally death. CBP directly interacts with Elk-1 in vitro and in vivo. Xing J., Kornhauser J. M., Xia Z., Thiele E. A., Greenberg M. E. (1998). sElk-1 arises from an internal translation start site in the Elk-1 sequence, which generates a protein lacking the first 54 amino acids of the Elk-1 DBD. Zhang H. M., Li L., Papadopoulou N., Hodgson G., Evans E., Galbraith M., Dear M., Vougier S., Saxton J., Shaw P. E. (2008). TCFs are able to form a ternary complex with the serum response factor (SRF) and the serum-response element (SRE), and are involved in SRE-driven gene expression. Glutamate induces phosphorylation of Elk-1 and CREB, along with c-fos activation, via an extracellular signal-regulated kinase-dependent pathway in brain slices. Hipskind R. A., Rao V. N., Mueller C. G., Reddy E. S., Nordheim A. See this image and copyright information in PMC. When Elk1 or SRF binding to DNA is blocked in the rat hippocampus, only sequestration of SRF interferes with long-term spatial memory. In conclusion, in the absence of specific pharmacological inhibitors, or genetic models aimed at specifically blunting Elk-1 Serine 383 phosphorylation, we cannot conclude about the causative link between this phosphorylation event, long-term neuronal plasticity and learning. (2002)described the R motif, a novel class of repression domain of Elk-1 that is located upstream the transactivation domain (Figure (Figure1).1). Signal transduction of pregnenolone sulfate in insulinoma cells: activation of Egr-1 expression involving TRPM3, voltage-gated calcium channels, ERK, and ternary complex factors. (1999). Altogether, these results highlight that Elk1 is an important component of drug addiction. alpha-Synuclein forms a complex with transcription factor Elk-1. Assay time: 3.5 hours (cell extracts preparation not included). It contains the lysine residues that are susceptible to be SUMOylated, a post-translational event that reinforce the repression exerted by the R domain. Abuse of heroin and prescription opiate medications has grown to disturbing levels. A. Yet, there is no direct evidence implicating Elk-1 in these processes. [6], Elk1 activation plays a central role in drug addiction. Addictive and non-addictive drugs induce distinct and specific patterns of ERK activation in mouse brain. This gene is a member of the Ets family of transcription factors and of the ternary complex factor (TCF) subfamily. Bernal-Mizrachi E, Wice B, Inoue H, Permutt MA. The protein encoded by this gene is a nuclear . . Hyperphosphorylation of ERK and Elk-1 in the nucleus accumbens (NAcc) is associated with the expression of methamphetamine- and cocaine-induced CPP (Mizoguchi et al., 2004; Miller and Marshall, 2005).

Accessibility In vivo protein transduction: delivery of a biologically active protein into the mouse. Future investigations should aim at deciphering if A derepresses PS1 expression by inhibiting Elk-1 activity in AD and/or FAD pathogenesis. Interestingly, the srf gene itself has been identified as an Elk-1 target (Kasza et al., 2005). Jenab S., Festa E. D., Nazarian A., Wu H. B., Sun W. L., Hazim R., Russo S. J., Quinones-Jenab V. (2005). Elk-1, a member of the ternary complex factor family of Ets domain proteins that bind serum response elements, is activated by phosphorylation in a cell-specific manner in response to growth factors and other agents. microRNA expression levels in the nucleus accumbens correlate with morphine-taking but not morphine-seeking behaviour in male rats. (1993). Dual MAP kinase pathways mediate opposing forms of long-term plasticity at CA3CA1 synapses.
