Summary: Enables phosphoprotein phosphatase activity. Predicted to be involved in several processes, including centrosome cycle; positive regulation of transcription by RNA polymerase II; and protein dephosphorylation. Predicted to act upstream of or within cellular response to xenobiotic stimulus and regulation of nucleocytoplasmic transport. Predicted to be located in several cellular components, including contractile muscle fiber; cytoskeleton; and kinetochore. Predicted to be part of PTW/PP1 phosphatase complex. Predicted to be active in A band and Z disc. Orthologous to human PPP1R12A (protein phosphatase 1 regulatory subunit 12A). [provided by Alliance of Genome Resources, Nov 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.
