    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 By similarity.By similarity

    Catalytic activityi

    [a protein]-serine/threonine phosphate + H2O = [a protein]-serine/threonine + phosphate.

    Cofactori

    Binds 2 manganese ions per subunit.By similarity
