Interestingly, stimulation of MAPK by osmotic stress results in a marked loss of phosphorylation at the PKA site S1445, but a concomitant increase in phosphorylation at S1448, presumably also by ERK. At present, we have no information as to what are the functional consequences of ERK or PKA phosphorylation of hScrib. However, we can speculate that this will most likely affect the ability of hScrib to interact with some of its cellular partners, and studies are currently in progress to investigate these aspects further.

Together, our data strongly suggest that modulation of neuronal N-type VDCCs by ERK involves phosphorylation of Ca(v)2.2alpha1 and to a lesser extent possibly also Ca(v)beta subunits. On the basis of the evidence presented here, it is therefore suggested that ERK-dependent up-regulation of Cav2.2 channels is primarily mediated by phosphorylation of Ser-447 on the I–II loop of Cav2.2 and possibly also the two SP sites conserved on Cavβs.

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.

Together, our data strongly suggest that modulation of neuronal N-type VDCCs by ERK involves phosphorylation of Ca(v)2.2alpha1 and to a lesser extent possibly also Ca(v)beta subunits. On the basis of the evidence presented here, it is therefore suggested that ERK-dependent up-regulation of Cav2.2 channels is primarily mediated by phosphorylation of Ser-447 on the I–II loop of Cav2.2 and possibly also the two SP sites conserved on Cavβs.

The molecular mechanism responsible for activation of NPC2-null cells was shown to be a sustained phosphorylation of ERK 1/2 mitogen-activated protein kinase (MAPK), which fulfills both the sufficient and necessary fibroblast activation criteria. All of these findings highlight a novel mechanism where NPC2 by negatively regulating ERK 1/2 MAPK phosphorylation may efficiently suppress development of maladaptive tissue remodeling and inflammation.

7535768	Dephosphorylation and Inactivation of ERKs\|ERK1 phosphorylated on either threonine (ERK1Y204F) or tyrosine alone (ERK1T202A) was utilized as a substrate for HVH2. Threonine 202 and tyrosine 204 in ERK1 (53) correspond to threonine 183 and tyrosine 185 in ERK2 which are the activation-phosphorylation sites by MEK(14, 15, 16). ERK1, a kinase-deficient mutant, was phosphorylated on both threonine and tyrosine by MEK2 (Fig. 3B). ERK1T202A, having threonine 202 substituted by an alanine, was phosphorylated only on tyrosine while ERK1Y204F, having tyrosine 204 substituted by a phenylalanine, was phosphorylated only on threonine (Fig. 3B). GST-HVH2 dephosphorylated all three ERK1 mutants (Fig. 3A), suggesting that double phosphorylations of adjacent threonine and tyrosine were not a prerequisite for HVH2 recognition. However, HVH2 dephosphorylated ERK1* and ERK1T202A more efficiently than ERK1Y204F (Fig. 3A), indicating that HVH2 preferred phosphotyrosine over phosphothreonine. Interestingly, MEK also phosphorylated tyrosine residues more efficiently than threonine residues of ERK

In contrast, we have found that stress-induced ERK1/2 activity is downregulated by ubiquitin/proteasome-mediated degradation of ERK1/2. The PHD domain of MEKK1, a RING finger-like structure, exhibited E3 ubiquitin ligase activity toward ERK2 in vitro and in vivo. Therefore, MEKK1 functions not only as an upstream activator of the ERK and JNK through its kinase domain, but also as an E3 ligase through its PHD domain, providing a negative regulatory mechanism for decreasing ERK1/2 activity.

10514499	Extracellular signal-regulated kinases (erks) phosphorylate the high molecular mass isoform of the actin-binding protein caldesmon (h-cad) at two sites (ser(759) and ser(789)) during smooth muscle stimulation. Nmr spectroscopy shows that the actin binding properties of the minimal inhibitory region of caldesmon, residues 750-779, alter upon map kinase phosphorylation of ser-759, a residue not involved in actin binding. This phosphorylation leads to markedly diminished actin affinity as a result of the loss of interaction at one of the two sites that bind to f-actin.

14768064	The precursor form of the cytokine il-16 (proil-16) was shown to be phosphorylated on ser144 in antigen receptor-, sdf1alpha- and il-2-activated t cells. Genetic and pharmacological-inhibitor experiments showed that the phosphorylation of proil-16 is dependent on activation of the kinases erk1/2. Il-16 is secreted by mitogen-activated t cells, and the biochemical link between proil-16 and erk1/2, revealed by studies with pap-1, prompted analysis of the role of map kinases in this response.

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.
