Protein
Calcium-dependent protein kinase 20
Gene
CPK20
Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Functioni
May play a role in signal transduction pathways that involve calcium as a second messenger.
Catalytic activityi
Activity regulationi
Activated by calcium. Autophosphorylation may play an important role in the regulation of the kinase activity (By similarity).By similarity

Domaini
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 (398-428) inactivates kinase activity under calcium-free conditions (By similarity).By similarity
Sequence similaritiesi
Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. CDPK subfamily.PROSITE-ProRule annotation
