a protein kinase of the CAMK2 family. A prominent kinase in the central nervous system that may function in long-term potentiation and neurotransmitter release. Member of the NMDAR signaling complex in excitatory synapses that may regulate NMDAR-dependent potentiation of the AMPAR and synaptic plasticity. The holoenzyme is composed of four different chains: alpha, beta, gamma, and delta. The different chains assemble into homo- or heteromultimeric holoenzymes composed of 8 to 12 subunits. May interact with BAALC, MPDZ, SYN1 and synGAP. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
