Camk2a (P11275) - Overview - Molecular Target Synopsis


Camk2a, Calcium/calmodulin-dependent protein kinase type II subunit alpha
Enzyme Classification
UniProt P11275

Also Known as KCC2A_RAT, 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 (PubMed:15312654). Regulates dendritic spine development. Also regulates the migration of developing neurons. Phosphorylates the transcription factor FOXO3 to activate its transcriptional activity (By similarity). There are 4 genes encoding calcium/calmodulin-dependent protein kinase type II chains: CAMK2A, CAMK2B, CAMK2G and CAMK2D. The corresponding proteins assemble into homo- or heteromultimeric holoenzymes composed of 12 subunits with two hexameric rings stacked one on top of the other (By similarity). Interacts with BAALC (PubMed:15659234). Interacts with MPDZ (PubMed:15312654). Interacts with SYN1 (PubMed:1328883). Interacts with CAMK2N2 (PubMed:9724800). Interacts with SYNGAP1 (PubMed:15312654). Interacts with SYNPO2 (PubMed:17923693). Interacts with SHANK3. Interacts with GRIN2B. Interacts with CACNB2. Interacts with LRRC7. Interacts with GRM5 (By similarity).
