Function

KCC2A_MOUSE Calcium/calmodulin-dependent protein kinase that functions autonomously after Ca(2+)/calmodulin-binding and autophosphorylation, and is involved in various processes, such as synaptic plasticity, neurotransmitter release and long-term potentiation (By similarity). 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 (By similarity). Also regulates the migration of developing neurons (By similarity). Phosphorylates the transcription factor FOXO3 to activate its transcriptional activity (PubMed:23805378). Phosphorylates the transcription factor ETS1 in response to calcium signaling, thereby decreasing ETS1 affinity for DNA (PubMed:15994560). In response to interferon-gamma (IFN-gamma) stimulation, catalyzes phosphorylation of STAT1, stimulating the JAK-STAT signaling pathway (By similarity). In response to interferon-beta (IFN-beta) stimulation, stimulates the JAK-STAT signaling pathway (By similarity). Acts as a negative regulator of 2-arachidonoylglycerol (2-AG)-mediated synaptic signaling via modulation of DAGLA activity (PubMed:23502535).[UniProtKB:P11275][UniProtKB:Q9UQM7]^[1] ^[2] ^[3] Has no kinase activity.^[4]

Publication Abstract from PubMed

We report the crystal structure of the 143 residue association domain of Ca(2+)/calmodulin-dependent protein kinase II (CaMKII). The association domain forms a hub-like assembly, composed of two rings of seven protomers each, which are stacked head to head and held together by extensive interfaces. The tetradecameric organization of the assembly was confirmed by analytical ultracentrifugation and multiangle light scattering. Individual protomers form wedge-shaped structures from which N-terminal helical segments that connect to the kinase domain extend toward the equatorial plane of the assembly, consistent with the arrangement of the kinase domains in a second outer ring. A deep and highly conserved pocket present within the association domain may serve as a docking site for proteins that interact with CaMKII.
