The menin-jund interaction blocks jun n-terminal kinase (jnk)-mediated jund phosphorylation and suppresses jund-induced transcription. We found a role for phosphorylation of the ser100 residue of jund;jund phosphorylation were prevented by inhibitors of calcium, calmodulin, or erk1/2 kinase.

12063245	Consensus phosphorylation sites for p42/44 MAPK and GSK-3 are present in the SP repeat of MCIP1 at serine 112 and serine 108, respectively \|Several endogenous proteins are capable of inhibiting the catalytic activity of calcineurin. Modulatory calcineurin interacting protein 1 (MCIP1) is unique among these proteins on the basis of its pattern of expression and its function in a negative feedback loop to regulate calcineurin activity. Here we show that MCIP1 can be phosphorylated by MAPK and glycogen synthase kinase-3 and that phosphorylated MCIP1 is a substrate for calcineurin.

Serine/threonine to alanine substitution abolishes hnRNP-E2 phosphorylation and markedly decreases its stability in BCR/ABL-expressing myeloid precursors.

10841026	More interestingly, ERK-dependent phosphorylation of MITF at Ser 73 is essential for MITF ubiquitinilation and degradation (87). Putting together all these findings, it can be proposed that MAPK activation inhibits melanogenesis due to an increased MITF degradation which is dependent on the MAPK-induced MITF phosphorylation and ubiquitinilation. In summary, although the phosphorylation of MITF at Ser73 increases its intrinsic transcriptional activity, this phosphorylation also targets MITF to the proteasome for its degradation. Consequently, the decrease in MITF levels leads to a down-regulation of melanogenic enzymes expression and to an inhibition of melanogenesis.

From our results, we speculate that activators of the MAPK pathway, such as growth factors, insulin, and certain oncoproteins, or inhibitors of CDK function, such as tumor growth factor beta (TGF_), p21, and p27, might attenuate receptor-induced transcrip- tional responses. In contrast, negative regulators of MAPK, such as pKA, as well as activators of CDK, such as the cyclins or CAKs, should potentiate receptor action.

By contrast, MARK and PKA phosphorylate several sites within the repeats (notably theKXGS motifs including Ser262, Ser324, and Ser356, plus Ser320); in addition PKA phosphorylates somesites in the flanking domains, notably Ser214. This type of phosphorylation strongly reduces tau’s affinityfor microtubules, and at the same time inhibits tau’s assembly into PHFs.

These sites were phosphorylated by extracellular signal-regulated kinase (erk)-1 in vitro, and their phosphorylation in vivo was dependent on endogenous erk activity. Functionally, erk-1 expression sustains raf-1 activation in a manner dependent on raf-1 phosphorylation on the identified sites, and s289/296/301a substitution markedly decreases the in vivo activity of raf-1 s259a.

Additionally, an Eps8 mutant, impaired in the MAPK target sites (S624A/T628A), displays increased association to actin-rich structures, is resistant to BDNF-mediated release from microfilaments, and inhibits BDNF-induced filopodia. The opposite is observed for a phosphomimetic Eps8 (S624E/T628E) mutant. Thus, collectively, our data identify Eps8 as a critical capping protein in the regulation of axonal filopodia and delineate a molecular pathway by which BDNF, through MAPK-dependent phosphorylation of Eps8, stimulates axonal filopodia formation, a process with crucial impacts on neuronal development and synapse formation.

15657420	The formation of rsk-nfatc4-dna transcription complex is also apparent upon adipogenesis. Bound rsk phosphorylates ser(676) and potentiates nfatc4 dna binding by escalating nfat-dna association. Ser(676) is also targeted by the erk map kinase, which interacts with nfat at a distinct region than rsk. Thus, integration of the erk/rsk signaling pathway provides a mechanism to modulate nfatc4 transcription activity.

Using phosphospecific antibody against this site, we show that this residue is actually phosphorylated in cells. We also show that phosphorylation of ser(69) promotes ubiquitination of bimel. We conclude that mek inhibitors sensitize mda-mb231 and hbc4 cells to anoikis by blocking phosphorylation and hence degradation of bimel

Among several putative ERK phosphorylation sites, we identified threonine 264 in the N-terminal ankyrin repeat domain as the most critical site for the ERK-dependent modulation of TRPV3 channel activity. Of note, Thr264 is in close vicinity to a structurally and functionally important TRPV3 region comprising an atypical finger 3 and oxygen-dependent hydroxylation site. In summary, our findings indicate that Thr264 in TRPV3 is a key ERK phosphorylation site mediating EGFR-induced sensitization of the channel to stimulate signaling pathways involved in regulating skin homeostasis.

Tr mutations in the proposed mapk docking domain and at residue 142 modulated t(4)-conditioned shedding of co-repressor and recruitment of co-activator proteins by the receptor, and they altered transcriptional activity of tr in a thyroid hormone response element-luciferase reporter assay.

Function	Serine/threonine kinase which acts as an essential component of the MAP kinase signal transduction pathway. MAPK1/ERK2 and MAPK3/ERK1 are the 2 MAPKs which play an important role in the MAPK/ERK cascade. They participate also in a signaling cascade initiated by activated KIT and KITLG/SCF. Depending on the cellular context, the MAPK/ERK cascade mediates diverse biological functions such as cell growth, adhesion, survival and differentiation through the regulation of transcription, translation, cytoskeletal rearrangements. The MAPK/ERK cascade plays also a role in initiation and regulation of meiosis, mitosis, and postmitotic functions in differentiated cells by phosphorylating a number of transcription factors. About 160 substrates have already been discovered for ERKs. Many of these substrates are localized in the nucleus, and seem to participate in the regulation of transcription upon stimulation. However, other substrates are found in the cytosol as well as in other cellular organelles, and those are responsible for processes such as translation, mitosis and apoptosis. Moreover, the MAPK/ERK cascade is also involved in the regulation of the endosomal dynamics, including lysosome processing and endosome cycling through the perinuclear recycling compartment (PNRC); as well as in the fragmentation of the Golgi apparatus during mitosis. The substrates include transcription factors (such as ATF2, BCL6, ELK1, ERF, FOS, HSF4 or SPZ1), cytoskeletal elements (such as CANX, CTTN, GJA1, MAP2, MAPT, PXN, SORBS3 or STMN1), regulators of apoptosis (such as BAD, BTG2, CASP9, DAPK1, IER3, MCL1 or PPARG), regulators of translation (such as EIF4EBP1) and a variety of other signaling-related molecules (like ARHGEF2, FRS2 or GRB10). Protein kinases (such as RAF1, RPS6KA1/RSK1, RPS6KA3/RSK2, RPS6KA2/RSK3, RPS6KA6/RSK4, SYK, MKNK1/MNK1, MKNK2/MNK2, RPS6KA5/MSK1, RPS6KA4/MSK2, MAPKAPK3 or MAPKAPK5) and phosphatases (such as DUSP1, DUSP4, DUSP6 or DUSP16) are other substrates which enable the propagation the MAPK/ERK signal to additional cytosolic and nuclear targets, thereby extending the specificity of the cascade.
