"In biochemistry, a phosphatase is an enzyme that uses water to cleave a phosphoric acid monoester into a phosphate ion and an alcohol. Because a phosphatase enzyme catalyzes the hydrolysis of its substrate, it is a subcategory of hydrolases. Phosphatase enzymes are essential to many biological functions, because phosphorylation (e.g. by protein kinases) and dephosphorylation (by ph… " - Phosphatase activators

WebThe Ser/Thr phosphatase PP2A constitutes about 1% of the total cellular protein content and is together with Protein Phosphatase 1 (PP1) responsible for more than 90% of all Ser/Thr phosphatase activity in the cell ( 49, 50 ). PP1 and PP2A are both holoenzymes, consisting of different subunits. WebCDC25A is a protein phosphatase that activates the CDK2/Cyclin E complex by removing the inhibitory phosphates from CDK2, promoting the progression of the cell cycle from G1 to S phase. However, in the case of a mutation in CDC25A resulting in constitutive activation, the protein phosphatase would always be active, leading to the continuous ...

The addition of a phosphate group may activate or de-activate an enzyme (e.g., kinase signalling pathways ) or enable a protein-protein interaction to occur (e.g., SH2 domains ); therefore phosphatases are integral to many signal transduction pathways. Phosphate addition and removal do not necessarily correspond to enzyme activation or inhibition, and that several e…
