Protein phosphatase 1

PP1 plays an instrumental role in glycogen metabolism through its responsibility for the interconversion between phosphorylase a and b.

Protein phosphatase 1 (PP1) belongs to a certain class of phosphatases known as protein serine/threonine phosphatases. This type of phosphatase includes metal-dependent protein phosphatases (PPMs) and aspartate-based phosphatases. PP1 has been found to be important in the control of glycogen metabolism, muscle contraction, cell progression, neuronal activities, splicing of RNA, mitosis,[1] cell division, apoptosis, protein synthesis, and regulation of membrane receptors and channels.[2]
