Calcium/calmodulin-dependent protein kinase type II subunit alpha
Calcium/calmodulin-dependent protein kinase type II subunit alpha (CAMKIIα), a.k.a. Ca2+/calmodulin-dependent protein kinase II alpha, is one subunit of CamKII, a protein kinase (i.e., an enzyme which phosphorylates proteins) that in humans is encoded by the CAMK2A gene.[5][6]
Function
The product of the CAMK2A gene is an enzyme that belongs to the serine/threonine-specific protein kinase family, as well as the Ca2+/calmodulin-dependent protein kinase II subfamily. Ca2+ signaling is crucial for several aspects of synaptic plasticity at glutamatergic synapses. This enzyme is composed of four different chains: alpha, beta, gamma, and delta. The alpha chain encoded by this gene is required for hippocampal long-term potentiation (LTP) and spatial learning. In addition to its calcium-calmodulin (CaM)-dependent activity, this protein can undergo autophosphorylation, resulting in CaM-independent activity. Two transcript variants encoding distinct isoforms have been identified for this gene.[7] According to a 2018 study by Bruno Reversade, the recessive mutation of CAMK2A in humans cause a syndrome of severe intellectual disability with growth retardation.[8]
