Ppp3r2 Gene Summary [Mouse]
Enables calcium-dependent protein serine/threonine phosphatase regulator activity. Acts upstream of or within penetration of zona pellucida. Located in sperm mitochondrial sheath. Part of calcineurin complex. Is expressed in several structures, including brain; lung; male reproductive gland or organ; renal vasculature; and upper jaw molar. Orthologous to human PPP3R2 (protein phosphatase 3 regulatory subunit B, 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 mouse Ppp3r2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
