General annotation (Comments)

Function

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.

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.

Enzyme regulation

The phosphatase activity of the PPP1R15A-PP1 complex toward EIF2S1 is specifically inhibited by Salubrinal, a drug that protects cells from endoplasmic reticulum stress. Ref.15

Subunit structure

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, PPP1R3B, PPP1R3C and PPP1R3D mediate binding to glycogen. Part of a complex containing PPP1R15B, PP1 and NCK1/2 By similarity. Component of the MLL5-L complex, at least composed of MLL5, STK38, PPP1CA, PPP1CB, PPP1CC, HCFC1, ACTB and OGT. Interacts with PPP1R7 and PPP1R12C. PPP1R15A and PPP1R15B mediate binding to EIF2S1.

Subcellular location

Cytoplasm By similarity.

Sequence similarities

Belongs to the PPP phosphatase family. PP-1 subfamily.
