Function
function
May play a role in signal transduction pathways that involve calcium as a second messenger.
Catalytic activity
- ATP + L-seryl-[protein] = ADP + H+ + O-phospho-L-seryl-[protein]
Activity regulation
Activated by calcium and calmodulin. 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 (408-438) inactivates kinase activity under calcium-free conditions (By similarity).
