Functioni

Protein phosphatase that associates with over 200 regulatory proteins to form highly specific holoenzymes which dephosphorylate hundreds of biological targets. Protein phosphatase 1 (PP1) is essential for cell division, and participates in the regulation of glycogen metabolism, muscle contractility and protein synthesis. Dephosphorylates RPS6KB1. Involved in regulation of ionic conductances and long-term synaptic plasticity. May play an important role in dephosphorylating substrates such as the postsynaptic density-associated Ca2+/calmodulin dependent protein kinase II. Component of the PTW/PP1 phosphatase complex, which plays a role in the control of chromatin structure and cell cycle progression during the transition from mitosis into interphase. In balance with CSNK1D and CSNK1E, determines the circadian period length, through the regulation of the speed and rhythmicity of PER1 and PER2 phosphorylation. May dephosphorylate CSNK1D and CSNK1E.2 Publications

Interactioni

Subunit structurei

PP1 comprises a catalytic subunit, PPP1CA, PPP1CB or PPP1CC, which is folded into its native form by inhibitor 2 and glycogen synthetase kinase 3, and then complexed to one or several targeting or regulatory subunits. PPP1R12A, PPP1R12B and PPP1R12C mediate binding to myosin. PPP1R3A (in skeletal muscle), PPP1R3B (in liver), PPP1R3C, PPP1R3D and PPP1R3F (in brain) mediate binding to glycogen. Interacts with PPP1R3B, PPP1R7 and CDCA2 (By similarity). Isoform 2 interacts with SPZ1. This interaction can prevent SPZ1 binding to the E-box and inhibits PPP1CC activity. PPP1R15A and PPP1R15B mediate binding to EIF2S1. Part of a complex containing PPP1R15B, PP1 and NCK1/2. Interacts with IKFZ1; the interaction targets PPP1CC to pericentromeric heterochromatin, dephosphorylates IKAROS, stabilizes it and prevents it from degradation. Interacts with NOM1 and PPP1R8. Component of the PTW/PP1 phosphatase complex, composed of PPP1R10/PNUTS, TOX4, WDR82, and PPP1CA or PPP1CB or PPP1CC. Interacts with PPP1R8. Interacts with NEK2. Interacts with NEK2. Interacts with URI1; the interaction is phosphorylation-dependent and occurs in a growth factor-dependent manner (By similarity). Isoform 2 interacts with PPP1R42; the interaction is direct. Interacts with FOXP3 (By similarity). Isoform 2 interacts with TMEM225 (via RVxF motif) (PubMed:25605614). Isoform 2, but not isoform 1, interacts with Sh3glb1 testis-specific isoform 3; this interaction leads to the inhibition of phosphatase activity (PubMed:17381077). Interacts with MKI67 (By similarity). Interacts with RRP1B; this targets PPP1CC to the nucleolus (By similarity). Found in a complex with PPP1CA, PPP1CC, SHC1 and PEAK1 (By similarity).By similarity7 Publications
