ENCODES a protein that exhibits phosphatase inhibitor activity; protein phosphatase inhibitor activity (ortholog); protein serine/threonine phosphatase inhibitor activity (ortholog); INVOLVED IN regulation of phosphatase activity (ortholog); ASSOCIATED WITH familial hypercholesterolemia (ortholog);
Enables protein serine/threonine phosphatase inhibitor activity. Involved in regulation of phosphatase activity. Predicted to be located in cytosol. Is expressed in alimentary system; cerebellum; ganglia; heart; and neural retina. Human ortholog(s) of this gene implicated in familial hypercholestero
The protein encoded by this gene is found primarily in cerebellar Purkinje cells, where it functions as a protein phosphatase inhibitor. The encoded protein is a substrate for cGMP-dependent protein kinase. An allele of this gene was discovered that increases susceptibility to hypercholesterolemia.
