Ppp3cb Gene Summary [Mouse]
Enables calmodulin-dependent protein phosphatase activity. Involved in several processes, including positive regulation of insulin secretion involved in cellular response to glucose stimulus; protein modification process; and skeletal muscle fiber development. Acts upstream of or within several processes, including circulatory system development; locomotion involved in locomotory behavior; and negative regulation of T cell mediated cytotoxicity. Located in T-tubule and Z disc. Is active in glutamatergic synapse. Is expressed in several structures, including brain; gastrocnemius muscle; genitourinary system; jaw skeleton; and tooth. 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, Apr 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 mouse 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.
