CAMK2A 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. Regulates dendritic spine development. Also regulates the migration of developing neurons. Phosphorylates the transcription factor FOXO3 to activate its transcriptional activity. Belongs to the protein kinase superfamily. CAMK Ser/Thr protein kinase family. CaMK subfamily. 2 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
