WebThis review will focus on the plant PP2C family of protein phosphatases. Biochemical and molecular genetic studies in Arabidopsis have identified PP2C enzymes as key players in plant signal transduction processes. For instance, the ABI1/ABI2 PP2Cs are central components in abscisic acid (ABA) signal transduction. Webthe regulation of signal transduction by protein phosphorylation through the actions of protein kinases and protein phosphatases. Other areas of interest focus on the actions of …

WebMay 3, 2012 · We next examined whether SH2 domain–containing phosphatase-1 (SHP-1), a Tyr phosphatase known to regulate BCR signaling upon BCR ligation (13–15), may be … A protein phosphatase is a phosphatase enzyme that removes a phosphate group from the phosphorylated amino acid residue of its substrate protein. Protein phosphorylation is one of the most common forms of reversible protein posttranslational modification (PTM), with up to 30% of all … See more Phosphorylation involves the transfer of phosphate groups from ATP to the enzyme, the energy for which comes from hydrolysing ATP into ADP or AMP. However, dephosphorylation releases phosphates into solution as free … See more Phosphatases act in opposition to kinases/phosphorylases, which add phosphate groups to proteins. The addition of a phosphate group may activate or de-activate an enzyme … See more Human genes that encode proteins with phosphoprotein phosphatase activity include: Protein serine/threonine phosphatase • See more Phosphatases can be subdivided based upon their substrate specificity. Serine/threonine PP (PPM/PPP) families Protein Ser/Thr … See more Many phosphatases are promiscuous with respect to substrate type, or can evolve quickly to change substrate.
