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 COMP:11604, ChEBI:CHEBI:15378, ChEBI:CHEBI:29999, ChEBI:CHEBI:30616, 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 -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000269|PubMed:12913141}; CC Lipid-anchor {ECO:0000269|PubMed:12913141}. CC -!- ALTERNATIVE PRODUCTS: CC Event=Alternative splicing; Named isoforms=2; CC Name=1; CC IsoId=Q42438-1; Sequence=Displayed; CC Name=2; CC IsoId=Q42438-2; Sequence=VSP_036290; 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 (321-351) 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}.
