Also known as: PR65
Summary: Predicted to enable several functions, including protein antigen binding activity; protein heterodimerization activity; and protein phosphatase regulator activity. Predicted to be involved in several processes, including T cell homeostasis; meiotic sister chromatid cohesion, centromeric; and negative regulation of intracellular signal transduction. Predicted to act upstream of or within several processes, including nuclear division; peptidyl-serine dephosphorylation; and positive regulation of extrinsic apoptotic signaling pathway in absence of ligand. Predicted to be located in several cellular components, including chromosome, centromeric region; lateral plasma membrane; and neuronal cell body. Predicted to be part of FAR/SIN/STRIPAK complex and protein phosphatase type 2A complex. Predicted to be active in cytosol; glutamatergic synapse; and nucleus. 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.
