Phosphatase signal transduction
WebPhosphatases play a key role in regulating signal transduction. It is known that phosphatases are specific for cleavage of either serine-threonine or tyrosine phosphate groups. To date, numerous compounds have been identified. This paper reviews the classification, roles and pharmacological of protein serine/threonine phosphates. … 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. An alternative structural … See more In the adult brain, PPs are essential for synaptic functions and are involved in the negative regulation of higher-order brain functions such as learning and memory.

WebPhosphorylation is the most common mechanism of regulating protein function and transmitting signals throughout the cell. While phosphorylation has been observed in bacterial proteins, it is considerably more pervasive … 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.

Aberrant signal transduction is a prerequisite for cancer progression and metastasis. The crosstalk of cancer cells with stromal cells, including fibroblasts and immune cells, further augments cancer progression and metastasis.
