  • Function
    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. Dephosphorylates the 'Ser-418' residue of FOXP3 in regulatory T-cells (Treg) from patients with rheumatoid arthritis, thereby inactivating FOXP3 and rendering Treg cells functionally defective (PubMed:23396208).
  • Sequence similarities
    Belongs to the PPP phosphatase family. PP-1 subfamily.
  • Cellular localization
    Cytoplasm. Nucleus. Nucleus, nucleoplasm. Nucleus, nucleolus. Highly mobile in cells and can be relocalized through interaction with targeting subunits. In the presence of PPP1R8 relocalizes from the nucleus to nuclear speckles.

Thank you for your email. As the antibody is currently out of stock, it will take approximately 3-4 weeks for a new batch to come into stock. I unfortunately can't hasten the process. Please contact us again if you have any additional questions.

Thank you for your enquiry. I checked this antibody, and the sequence of the peptide used to generate ab16369 was indeed PRTANPPKKR, corresponding to amino acids 318-327 of Human PPP1B. However, the database links were wrong and I have updated them. Th...
