== Function ==
-
[[Ca2+/Calmodulin dependent protein kinase]] (CaMK) phosphorylates Ser and Thr. It is regulated by Ca<sup>2+</sup>/[[Calmodulin]] (CaM). It contains an N-terminal catalytic domain, regulatory domain (CBD) and association domain (ASD). CaMKI is a specialized CaM kinase while CaMKII is multifunctional kinase. '''CASK''' is a membrane associated CaMK. '''DAPK''' is a death-associated CaMK which protects cells from some programmed cell death. It contains a regulatory (RD) and autoinhibitory (AD) domains. The images at the left and at the right correspond to one representative CaMK, ''i.e.'' crystal structure of human native membrane associated Ca<sup>2+</sup>/Calmodulin dependent protein kinase ([[3mfr]]).

== Structural highlights ==
 +
CAMKII contains an N-terminal catalytic domain which binds ATP and substrate protein, regulatory domain (CBD) and association domain (ASD). DAPK contains a regulatory (RD) and autoinhibitory (AD) domains. The activity of human CamKII is regulated by autophosphorylation of <scene name='41/415817/Cv/3'>Thr 286</scene> and Thr 305 (T305 is not in the pdb file). <ref>PMID:20668654</ref>
