Ppp1cb Gene Summary [Rat]
Enables phosphoprotein phosphatase activity. Involved in protein dephosphorylation; regulation of glycogen biosynthetic process; and regulation of glycogen catabolic process. Located in glycogen granule. Part of protein phosphatase type 1 complex. Human ortholog(s) of this gene implicated in Noonan syndrome-like disorder with loose anagen hair 2. Orthologous to human PPP1CB (protein phosphatase 1 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 Ppp1cb often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
