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 (391-421) 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
Contains 4 EF-hand domains.Curated
Contains 1 protein kinase domain.PROSITE-ProRule annotation

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
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.
