Function

[KCC1A_RAT] Calcium/calmodulin-dependent protein kinase that operates in the calcium-triggered CaMKK-CaMK1 signaling cascade and, upon calcium influx, regulates transcription activators activity, cell cycle, hormone production, cell differentiation, actin filament organization and neurite outgrowth. Recognizes the substrate consensus sequence [MVLIF]-x-R-x(2)-[ST]-x(3)-[MVLIF]. Regulates axonal extension and growth cone motility in hippocampal and cerebellar nerve cells. Upon NMDA receptor-mediated Ca(2+) elevation, promotes dendritic growth in hippocampal neurons and is essential in synapses for full long-term potentiation (LTP) and ERK2-dependent translational activation. Downstream of NMDA receptors, promotes the formation of spines and synapses in hippocampal neurons by phosphorylating ARHGEF7/BETAPIX on 'Ser-516', which results in the enhancement of ARHGEF7 activity and activation of RAC1. Promotes neuronal differentiation and neurite outgrowth by activation and phosphorylation of MARK2 on 'Ser-91', 'Ser-92', 'Ser-93' and 'Ser-294'. Promotes nuclear export of HDAC5 and binding to 14-3-3 by phosphorylation of 'Ser-259' and 'Ser-498' in the regulation of muscle cell differentiation (By similarity). Regulates NUMB-mediated endocytosis by phosphorylation of NUMB on 'Ser-275' and 'Ser-294'. Involved in the regulation of basal and estrogen-stimulated migration of medulloblastoma cells through ARHGEF7/BETAPIX phosphorylation (By similarity). Is required for proper activation of cyclin-D1/CDK4 complex during G1 progression in diploid fibroblasts. Plays a role in K(+) and ANG2-mediated regulation of the aldosterone synthase (CYP11B2) to produce aldosterone in the adrenal cortex. Phosphorylates EIF4G3/eIF4GII. In vitro phosphorylates CREB1, ATF1, CFTR, MYL9 and SYN1/synapsin I.^[1] ^[2] ^[3] ^[4] ^[5] ^[6] ^[7] ^[8]

Publication Abstract from PubMed

The crystal structure of calcium/calmodulin-dependent protein kinase I has been determined in the autoinhibited form. The C-terminal regulatory region of the enzyme forms a helix-loop-helix segment that extends across the two domains of the catalytic core, making multiple inhibitory interactions. Elements of the first regulatory alpha helix and the loop interfere with the binding site for peptide substrates, while the loop and the second helix interact with the ATP-binding domain to induce conformational changes that obstruct the nucleotide binding pocket. One part of the calmodulin recognition element protrudes away from the catalytic domain and is potentially available for an initial interaction with calmodulin. The structure provides a view of an intact calmodulin target and suggests that substantial structural changes will accompany kinase activation by calmodulin binding to the regulatory region.

Structural basis for the autoinhibition of calcium/calmodulin-dependent protein kinase I.,Goldberg J, Nairn AC, Kuriyan J Cell. 1996 Mar 22;84(6):875-87. PMID:8601311^[9]
