General annotation (Comments)

Function

CaM-kinase II (CAMK2) is a prominent kinase in the central nervous system that may function in long-term potentiation and neurotransmitter release.

Catalytic activity

ATP + a protein = ADP + a phosphoprotein.

Enzyme regulation

Autophosphorylation of CAMK2 plays an important role in the regulation of the kinase activity.

Subunit structure

CAMK2 is composed of four different chains: alpha, beta, gamma, and delta. The different isoforms assemble into homo- or heteromultimeric holoenzymes composed of 8 to 12 subunits. Interacts with RRAD By similarity.

Tissue specificity

Expressed in cardiac muscle and skeletal muscle. Isoform Delta 3, isoform Delta 2, isoform Delta 8 and isoform Delta 9 are expressed in cardiac muscle. Isoform Delta 11 is expressed in skeletal muscle. Ref.1

Miscellaneous

Expression of CAMK2D is significantly increased in patients suffering from dilated cardiomyopathy.

Sequence similarities

Belongs to the protein kinase superfamily. CAMK Ser/Thr protein kinase family. CaMK subfamily.

Contains 1 protein kinase domain.
