Protein

Calcium-dependent protein kinase 4

Gene

CPK4

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

May play a role in signal transduction pathways that involve calcium as a second messenger. Functions as regulator of the calcium-mediated abscisic acid (ABA) signaling pathway. Phosphorylates ABA-responsive transcription factors ABF1 and ABF4 in vitro. Phosphorylates the nuclear zinc finger Di19 in vitro.2 Publications

Catalytic activityi

ATP + a protein = ADP + a phosphoprotein.

Enzyme regulationi

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

Domaini

There is 3 contiguous domains conserved in the CDPK subfamily: a kinase domain, an autoinhibitory (junction) domain and a calmodulin-like domain. The autoinhibitory domain (289-319) inactivates kinase activity under calcium-free conditions (By similarity).By similarity

100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
