General annotation (Comments)

Function	Calcium/calmodulin-dependent protein kinase belonging to a proposed calcium-triggered signaling cascade. In vitro phosphorylates transcription factor CREB1 By similarity.
Catalytic activity	ATP + a protein = ADP + a phosphoprotein.
Enzyme regulation	Activated by Ca2+/calmodulin. Binding of calmodulin is thought to result in a conformational change and leads to activation through phosphorylation by CAMKK1 By similarity.
Subcellular location	Cytoplasm By similarity. Golgi apparatus membrane; Peripheral membrane protein By similarity. Cell membrane; Peripheral membrane protein By similarity.
Tissue specificity	Mainly expressed in brain with small amounts in skeletal muscles, kidney, spleen and liver. Strongly expressed in forebrain neocortex, striatum and limbic system. Ref.2
Domain	The autoinhibitory domain overlaps with the calmodulin binding region and interacts in the inactive folded state with the catalytic domain as a pseudosubstrate By similarity.
Post-translational modification	May be prenylated on Cys-473 By similarity.
Sequence similarities	Belongs to the protein kinase superfamily. CAMK Ser/Thr protein kinase family. CaMK subfamily. Contains 1 protein kinase domain.
