WebProtein phosphatases are the enzymes that hydrolyze phospho-ester bonds in phosphorylated proteins. They play critical roles in cell regulation, given their ability to reverse the effects of protein kinases. Protein phosphatases are divided between (phospho)serine/threonine (Ser/Thr) and (phospho)tyrosine (Tyr) phosphatases. Protein tyrosine phosphatases (EC 3.1.3.48, systematic name protein-tyrosine-phosphate phosphohydrolase) are a group of enzymes that remove phosphate groups from phosphorylated tyrosine residues on proteins: [a protein]-tyrosine phosphate + H2O = [a protein]-tyrosine + phosphate Protein … See more Together with tyrosine kinases, PTPs regulate the phosphorylation state of many important signalling molecules, such as the MAP kinase family. PTPs are increasingly viewed as integral components of signal transduction cascades, … See more Individual PTPs may be expressed by all cell types, or their expression may be strictly tissue-specific. Most cells express 30% to 60% of all the PTPs, however hematopoietic See more • This article incorporates text from the public domain Pfam and InterPro: IPR000106 See more By mechanism PTP activity can be found in four protein families.
