Summary: Predicted to enable protein serine/threonine phosphatase activity and transmembrane transporter binding activity. Acts upstream of or within several processes, including apoptotic mitochondrial changes; proteasome-mediated ubiquitin-dependent protein catabolic process; and response to hydrogen peroxide. Located in cytoplasm. Part of protein phosphatase type 2A complex. Is expressed in several structures, including cardiovascular system; central nervous system; eye; genitourinary system; and gut. Orthologous to human PPP2CB (protein phosphatase 2 catalytic subunit beta). [provided by Alliance of Genome Resources, Dec 2024]

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.
