Protein

Serine/threonine-protein phosphatase PP1-beta catalytic subunit

Gene

Ppp1cb

Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Protein phosphatase that associates with over 200 regulatory proteins to form highly specific holoenzymes which dephosphorylate hundreds of biological targets. Protein phosphatase (PP1) is essential for cell division, it participates in the regulation of glycogen metabolism, muscle contractility and protein synthesis. Involved in regulation of ionic conductances and long-term synaptic plasticity. 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

Catalytic activityi

[a protein]-serine/threonine phosphate + H2O = [a protein]-serine/threonine + phosphate.
[Myosin light-chain] phosphate + H2O = [myosin light-chain] + phosphate.

Cofactori

Mn2+By similarityNote: Binds 2 manganese ions per subunit.By similarity

Enzyme regulationi

Inhibited by the toxins okadaic acid, tautomycin and microcystin Leu-Arg. The phosphatase activity of the PPP1R15A-PP1 complex toward EIF2S1 is specifically inhibited by Salubrinal, a drug that protects cells from endoplasmic reticulum stress (By similarity).By similarity

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. The targeting or regulatory subunits determine the substrate specificity of PP1. 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. Component of the MLL5-L complex, at least composed of KMT2E/MLL5, STK38, PPP1CA, PPP1CB, PPP1CC, HCFC1, ACTB and OGT. Interacts with PPP1R7 and PPP1R12C. Interacts with PPP1R12A and NUAK1; the interaction is direct. Interacts with TRIM28; the interaction is weak (By similarity). Interacts with PPP1R15A; the interaction mediates binding to EIF2S1. Interacts with PPP1R16B. Component of the PTW/PP1 phosphatase complex, composed of PPP1R10/PNUTS, TOX4, WDR82, and PPP1CA or PPP1CB or PPP1CC. Interacts with PPP1R8. Interacts with TRIM28; the interaction is weak (By similarity). Part of a complex containing PPP1R15B, PP1 and NCK1/2. Interacts with PPP1R15B; the interaction mediates binding to EIF2S1.By similarity2 Publications
