General annotation (Comments)
| 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 By similarity. |
| Catalytic activity | A phosphoprotein + H2O = a protein + phosphate. |
| Cofactor | Binds 1 iron ion per subunit By similarity. Binds 1 manganese ion per subunit By similarity. |
| Subcellular location | |
| Sequence similarities | Belongs to the PPP phosphatase family. PP-1 subfamily. |
