3.1.3.16 protein-serine/threonine phosphataseIUBMB Comments
A group of enzymes removing the serine- or threonine-bound phosphate group from a wide range of phosphoproteins, including a number of enzymes that have been phosphorylated under the action of a kinase (cf. EC 3.1.3.48 protein-tyrosine-phosphatase). The spleen enzyme also acts on phenolic phosphates and phosphamides (cf. EC 3.9.1.1, phosphoamidase).

physiological function
physiological function
-
PP5 enhances thermotolerance via forming multi-chaperone complexes with heat shock protein 90.2 under heat shock conditions (42°C) in Arabidopsis
physiological function
-
protein phosphatase 1 participates in cell cycle regulation, salinity tolerance, cytokinin production, embryo development, blue-light signaling, cell differentiation, cell patterning, cell division, and gene silencing. Protein phosphatase 2A is intimately involved in regulating intracellular responses to brassinosteroids. Functions of PP5 include roles in disease resistance, thermotolerance, and light detection, while PP7 is implicated in several sensory functions, in particular, light sensing through the regulation of cryptochrome and phytochrome

reduced expression of phosphotyrosyl phosphatase activator leads to decreased protein phosphatase 2A (PP2A) activity. In particular, phosphotyrosyl phosphatase activator deficiency leads to decreased methylation in PP2A-C subunits. Complete loss of PP2Ac methylation leads to 30% reduction of PP2A activity
