Ppp3cb Gene Summary [Rat]
Enables calcium-dependent protein serine/threonine phosphatase activity and calmodulin binding activity. Involved in several processes, including muscle cell cellular homeostasis; positive regulation of insulin secretion involved in cellular response to glucose stimulus; and response to amphetamine. Located in plasma membrane. Part of protein-containing complex. Is active in synapse. Biomarker of schizophrenia. Human ortholog(s) of this gene implicated in aortic valve stenosis. Orthologous to human PPP3CB (protein phosphatase 3 catalytic subunit beta). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Ppp3cb often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
