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

CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000250|UniProtKB:Q9UQM7};
CC -!- ACTIVITY REGULATION: Activated by Ca(2+)/calmodulin. Binding of
CC calmodulin results in conformational change that relieves intrasteric
CC autoinhibition and allows autophosphorylation of Thr-286 which turns
CC the kinase in a constitutively active form and confers to the kinase a
CC Ca(2+)-independent activity. {ECO:0000250|UniProtKB:Q9UQM7}.
CC -!- SUBUNIT: There are 4 genes encoding calcium/calmodulin-dependent
CC protein kinase type II chains: CAMK2A, CAMK2B, CAMK2G and CAMK2D. The
CC corresponding proteins assemble into homo- or heteromultimeric
CC holoenzymes composed of 12 subunits with two hexameric rings stacked
CC one on top of the other (By similarity). Interacts with BAALC.
CC Interacts with MPDZ. Interacts with SYN1. Interacts with CAMK2N2.
CC Interacts with SYNGAP1. Interacts with SYNPO2 (By similarity).
CC Interacts with SHANK3. Interacts with GRIN2B. Interacts with CACNB2.
CC Interacts with LRRC7. Interacts with GRM5 (By similarity). Interacts
CC with DAGLA (via C-terminal); this interaction is enhanced by
CC autophosphorylation of CAMK2A at Thr-286 (By similarity). Interacts
CC with CAMK2N1; this interaction requires CAMK2A activation by Ca(2+) (By
CC similarity). {ECO:0000250|UniProtKB:P11275,
CC ECO:0000250|UniProtKB:P11798, ECO:0000250|UniProtKB:Q9UQM7}.
CC -!- SUBCELLULAR LOCATION: Synapse {ECO:0000250|UniProtKB:P11275}.
CC Postsynaptic density {ECO:0000250|UniProtKB:P11275}. Cell projection,
CC dendritic spine {ECO:0000250|UniProtKB:Q9UQM7}. Cell projection,
CC dendrite {ECO:0000250|UniProtKB:Q9UQM7}. Note=Postsynaptic lipid rafts.
CC {ECO:0000250|UniProtKB:P11275}.

CC Name=A;
CC IsoId=Q5RCC4-1; Sequence=Displayed;
CC Name=B;
CC IsoId=Q5RCC4-2; Sequence=VSP_014224;
CC -!- PTM: Autophosphorylation of Thr-286 following activation by
CC Ca(2+)/calmodulin. Phosphorylation of Thr-286 locks the kinase into an
CC activated state. {ECO:0000250|UniProtKB:Q9UQM7}.

CC -!- SIMILARITY: Belongs to the protein kinase superfamily. CAMK Ser/Thr
CC protein kinase family. CaMK subfamily. {ECO:0000305}.
