Summary: Enables protein serine/threonine phosphatase activity. Involved in entrainment of circadian clock by photoperiod; protein dephosphorylation; and regulation of macromolecule biosynthetic process. Acts upstream of or within branching morphogenesis of an epithelial tube; lung development; and positive regulation of extrinsic apoptotic signaling pathway in absence of ligand. Located in cytoplasm and nucleoplasm. Part of protein phosphatase type 1 complex. Is expressed in several structures, including cerebral cortex; esophagus; eye; and respiratory system. Orthologous to human PPP1CA (protein phosphatase 1 catalytic subunit alpha). [provided by Alliance of Genome Resources, Nov 2024]

Data, including data from studies using transgenic/knockout mice, suggest that Ppp1ca and Gnb1 interact in quiescent platelets; then, Ppp1ca and Plcb3 interact during platelet aggregation; thus, Gnb1 enlists Ppp1ca to modulate G protein-coupled receptor signaling. (Ppp1ca = protein phosphatase 1, catalytic subunit alpha; Gnb1 = guanine nucleotide-binding protein, subunit beta-1; Plcb3 = phospholipase C, subunit beta-3)

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.
