Ppp1r3b Gene Summary [Rat]
Enables [phosphorylase] phosphatase activity; enzyme binding activity; and protein phosphatase regulator activity. Contributes to phosphoprotein phosphatase activity. Involved in regulation of glycogen biosynthetic process and regulation of glycogen catabolic process. Located in glycogen granule. Part of protein phosphatase type 1 complex. Orthologous to human PPP1R3B (protein phosphatase 1 regulatory subunit 3B). [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 Ppp1r3b often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
