Ppp2r1a

Enables protein serine/threonine phosphatase activity. Involved in T cell homeostasis and negative regulation of phosphatidylinositol 3-kinase/protein kinase B signal transduction. Acts upstream of or within several processes, including nuclear division; peptidyl-serine dephosphorylation; and positive regulation of extrinsic apoptotic signaling pathway in absence of ligand. Located in cytosol. Part of protein phosphatase type 2A complex. Is active in glutamatergic synapse. Is expressed in several structures, including branchial arch; central nervous system; genitourinary system; limb; and sensory organ. Human ortholog(s) of this gene implicated in autosomal dominant intellectual developmental disorder 36. Orthologous to human PPP2R1A (protein phosphatase 2 scaffold subunit Aalpha).

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 Ppp2r1a often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
