CC -!- FUNCTION: May play a role in signal transduction pathways that involve
CC calcium as a second messenger.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-seryl-[protein] = ADP + H(+) + O-phospho-L-seryl-
CC [protein]; Xref=Rhea:RHEA:17989, Rhea:RHEA-COMP:9863, Rhea:RHEA-

CC ChEBI:CHEBI:83421, ChEBI:CHEBI:456216; EC=2.7.11.1;
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-threonyl-[protein] = ADP + H(+) + O-phospho-L-
CC threonyl-[protein]; Xref=Rhea:RHEA:46608, Rhea:RHEA-COMP:11060,
CC Rhea:RHEA-COMP:11605, ChEBI:CHEBI:15378, ChEBI:CHEBI:30013,
CC ChEBI:CHEBI:30616, ChEBI:CHEBI:61977, ChEBI:CHEBI:456216;
CC EC=2.7.11.1;
CC -!- ACTIVITY REGULATION: Activated by calcium. Autophosphorylation may play
CC an important role in the regulation of the kinase activity (By
CC similarity). {ECO:0000250}.
CC -!- DOMAIN: There are 3 contiguous domains conserved in the CDPK subfamily:
CC a kinase domain, an autoinhibitory (junction) domain and a calmodulin-
CC like domain. The autoinhibitory domain (329-359) inactivates kinase
CC activity under calcium-free conditions (By similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the protein kinase superfamily. Ser/Thr protein
CC kinase family. CDPK subfamily. {ECO:0000255|PROSITE-ProRule:PRU00159}.
