PP2A is a serine/threonine phosphatase that downregulates the MAP kinase pathway and subsequently modulates mitogenic signaling. This phosphatase also mediates localization of Sgo1 at centromeres, Ras-1 activation, and chromosome segregation. The catalytic subunit of PP2A (PP2Ac) regulates the signaling pathway for glucose-stiμLated insulin secretion .
特異性
Monoclonal Anti-PP2Ac is specific for the α and β isoforms of PP2Ac in humans, rats and mice. The antibody has not been tested in other species for cross-reactivity.
應用
MonoclonalAnti-PP2A, C subunit antibody produced in mouse has been used in immunoblotting and immunoprecipitation.
生化/生理作用
Protein phosphatase 2A (PP2A) is implicated in the negative control of cell growth and division. PP2Ac undergoes two post-translational modifications, phosphorylation and methylation, which are involved in the regulation of the enzyme activity.

Among various phosphatases, the protein phosphatase 2A (PP2A) is relatively well studied in the islet. Previously, we have demonstrated that the catalytic subunit of PP2A (PP2Ac) undergoes okadaic acid (OKA)-sensitive, reversible carboxylmethylation (CML), which appears to be requisite for glucose-stimulated
Endogenous cardiac pacemaker function regulates the rate and rhythm of cardiac contraction. The mutation p.Lys23Glu in the cohesin protein Shugoshin-1 causes severe heart arrhythmias due to sinoatrial node dysfunction and a debilitating gastrointestinal motility disorder, collectively termed the Chronic Atrial
Entry into mitosis is triggered by activation of Cdk1 and inactivation of its counteracting phosphatase PP2A/B55. Greatwall kinase inactivates PP2A/B55 via its substrates Ensa and ARPP19. Both Greatwall and Ensa/ARPP19 are regulated by phosphorylation, but the dynamic regulation of Greatwall
