Function

function

May play a role in signal transduction pathways that involve calcium as a second messenger.

Catalytic activity

Activity regulation

Activated by calcium. Autophosphorylation may play an important role in the regulation of the kinase activity (By similarity).

Domain

There are 3 contiguous domains conserved in the CDPK subfamily: a kinase domain, an autoinhibitory (junction) domain and a calmodulin-like domain. The autoinhibitory domain (288-318) inactivates kinase activity under calcium-free conditions (By similarity).

Sequence similarities

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