10753652	Skeletal muscle CaMKII enriches in nuclei and phosphorylates myogenic factor SRF at multiple sites. \| Microsequencing of these phosphorylated peptides identified that both Ser-103 and a novel residue, Thr-160 in the MADS box of SRF, were sites of phosphorylation. \| The location of Thr-160 in the 3-D structure of SRF suggests that its phosphorylation by nuclear CaMKII may directly influence DNA binding of SRF and other MADS box factors.

10347170	We show that serines 1046/1047 are sites for CaM kinase II phosphorylation, although there is a preference for serine 1047, which resides within the consensus -R-X-X-S-. In addition, we have identified major phosphorylation sites at serine 1142 and serine 1057, which lie within a novel -S-X-D- consensus. Mutation of serines 1046/1047 in full-length EGFR enhanced both fibroblast transformation and tyrosine autokinase activity that was significantly potentiated by additional mutation of serines 1057 and 1142. A single CaM kinase II site was also identified at serine 744 within sub-kinase domain III, and autokinase activity was significantly affected by mutation of this serine to an aspartic acid making this site appear constitutively phosphorylated. We have addressed the mechanism by which CaM kinase II phosphorylation of the EGFR might regulate receptor autokinase activity and show that this modification can hinder association of the cytoplasmic tail with the kinase domain to prevent an enzyme-substrate interaction.

We show that serine 1303 in the full-length NR2B and/or the cognate site in NR2A is a major site of phosphorylation of the receptor both in the postsynaptic density fraction and in living hippocampal neurons.

This residue is nested in a classical nuclear export sequence, and phosphorylated Ser-271 5-LO was exclusively found in the nucleus by immunofluorescence and by fractionation techniques\|Nuclear export of 5-LO can also be induced by KN-93, an inhibitor of Ca2+/calmodulin-dependent kinase II, and the effects of SB 203,580 plus KN-93 are additive. Finally, HeLa cells, which lack nuclear 5-LO, also lack constitutive phosphorylation of Ser-271. Taken together, these results indicate that the phosphorylation of Ser-271 serves to inhibit the nuclear export of 5-LO.

Replacement of Ser847 with Ala (S847A) prevented phosphorylation by CaM kinases. Phosphorylated recombinant wild-type nNOS at Ser847 (approximately 0.5 mol of phosphate incorporation into nNOS) exhibited a 30% decrease of Vmax with little change of both the Km for L-arginine and Kact for CaM relative to unphosphorylated enzyme. The activity of mutant S847D was decreased to a level 50-60% as much as the wild-type enzyme. The decreased NOS enzyme activity of phosphorylated nNOS at Ser847 and mutant S847D was partially due to suppression of CaM binding, but not to impairment of dimer formation which is thought to be essential for enzyme activation.

9813144	The point mutation T38D localized within the optimal CaMKII recognition motif of ICAP-1alpha results in a strong defect in cell spreading which cannot be overcome by the inhibition of the endogenous CaMKII. This fact strongly suggests that the phosphorylation of Threonine 38 by CaMKII modulates the alpha5beta1 integrin function. Conversely, the mutation T38A produces an analog of ICAP-1alpha that cannot be phosphorylated and that stimulates cell spreading on fibronectin to a similar extent when CaMKII is inhibited.

12486117	We show that chat is differentially phosphorylated by protein kinase c (pkc) isoforms on four serines (ser-440, ser-346, ser-347, and ser-476) and one threonine (thr-255). This phosphorylation is hierarchical, with phosphorylation at ser-476 required for phosphorylation at other serines. Phosphorylation at some, but not all, sites regulates basal catalysis and activation.

11052931	The most abundant signaling protein in the PSD fraction is Ca2+/calmodulin–dependent protein kinase II (CaMKII), which makes up 1 to 2% of the total protein in the forebrain (21). CaMKII is a target for Ca2+ flowing through the NMDA receptor and is necessary for normal synaptic plasticity in pyramidal neurons. The cytosolic tails of the NR2 subunits of the NMDA receptor bind to CaMKII and thus can serve as docking sites for it in the PSD

Function	Calcium/calmodulin-dependent protein kinase that functions autonomously after Ca(2+)/calmodulin-binding and autophosphorylation, and is involved in synaptic plasticity, neurotransmitter release and long-term potentiation. Member of the NMDAR signaling complex in excitatory synapses, it regulates NMDAR-dependent potentiation of the AMPAR and therefore excitatory synaptic transmission (By similarity). Regulates dendritic spine development (PubMed:28130356). Also regulates the migration of developing neurons (PubMed:29100089). Phosphorylates the transcription factor FOXO3 to activate its transcriptional activity (PubMed:23805378). Acts as a negative regulator of 2-arachidonoylglycerol (2-AG)-mediated synaptic signaling via modulation of DAGLA activity (By similarity).
