Phosphatase pp1
WebApr 5, 2024 · PP1 is an ubiquitous serine/threonine phosphatase that regulates many cellular processes, including cell division. It is expressed in mammalian cells as three closely related isoforms, alpha, beta/delta and gamma, which have distinct localization patterns. This gene encodes the gamma isozyme.

WebPP1 works by using two manganese ions as catalysts for the dephosphorylation (see below). Surrounding these ions is a Y-shaped cleft with three grooves: a hydrophobic, an acidic, and a C-terminal groove. When PP1 is not bonded to any other subunit, it is not particularly specific. Myosin phosphatase is made of three subunits. The catalytic subunit, PP1, is one of the more important Ser/Thr phosphatases in eukaryotic cells, as it plays a role in glycogen metabolism, intracellular transport, protein synthesis, and cell division as well as smooth muscle contraction. Because it is so important to basic cellular functions, and because there are far fewer protein phosphatase…
