Summary: 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).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
