UniProtKB - Q9Z2G7 (GRK7_ICTTR)
Protein
Rhodopsin kinase GRK7
Gene
GRK7
Organism
Ictidomys tridecemlineatus (Thirteen-lined ground squirrel) (Spermophilus tridecemlineatus)
Status
Functioni
Retina-specific kinase involved in the shutoff of the photoresponse and adaptation to changing light conditions via cone opsin phosphorylation, including rhodopsin (RHO).
By similarityMiscellaneous
Although the protein is present in a diversity of vertebrates ranging from bony fish to mammals, the mouse and rat orthologous proteins do not exist.
Catalytic activityi
Activity regulationi
Inhibited by phosphorylation of Ser-34.By similarity
