Anti-PP2A alpha + beta antibody [EPR11787(B)],Abcam,AB168350

Target data Catalytic subunit of protein phosphatase 2A (PP2A), a serine/threonine phosphatase involved in the regulation of a wide variety of enzymes, signal transduction pathways, and cellular events (PubMed : 10801873, PubMed : 12473674, PubMed : 17245430, PubMed : 22613722, PubMed : 33243860, PubMed : 34004147, PubMed : 9920888). PP2A is the major phosphatase for microtubule-associated proteins (MAPs) (PubMed : 22613722). PP2A can modulate the activity of phosphorylase B kinase casein kinase 2, mitogen-stimulated S6 kinase, and MAP-2 kinase (PubMed : 22613722). Cooperates with SGO2 to protect centromeric cohesin from separase-mediated cleavage in oocytes specifically during meiosis I (By similarity). Can dephosphorylate various proteins, such as SV40 large T antigen, AXIN1, p53/TP53, PIM3, WEE1 (PubMed : 10801873, PubMed : 12473674, PubMed : 17245430, PubMed : 9920888). Activates RAF1 by dephosphorylating it at 'Ser-259' (PubMed : 10801873). Mediates dephosphorylation of WEE1, preventing its ubiquitin-mediated proteolysis, increasing WEE1 protein levels, and promoting the G2/M checkpoint (PubMed : 33108758). Mediates dephosphorylation of MYC; promoting its ubiquitin-mediated proteolysis : interaction with AMBRA1 enhances interaction between PPP2CA and MYC (PubMed : 25438055). Mediates dephosphorylation of FOXO3; promoting its stabilization : interaction with AMBRA1 enhances interaction between PPP2CA and FOXO3 (PubMed : 30513302). Catalyzes dephosphorylation of the pyrin domain of NLRP3, promoting assembly of the NLRP3 inflammasome (By similarity). Together with RACK1 adapter, mediates dephosphorylation of AKT1 at 'Ser-473', preventing AKT1 activation and AKT-mTOR signaling pathway (By similarity). Dephosphorylation of AKT1 is essential for regulatory T-cells (Treg) homeostasis and stability (By similarity). Catalyzes dephosphorylation of PIM3, promoting PIM3 ubiquitination and proteasomal degradation (PubMed : 12473674). Part of the striatin-interacting phosphatase and kinase (STRIPAK) complexes (PubMed : 33633399). STRIPAK complexes have critical roles in protein (de)phosphorylation and are regulators of multiple signaling pathways including Hippo, MAPK, nuclear receptor and cytoskeleton remodeling (PubMed : 33633399). Different types of STRIPAK complexes are involved in a variety of biological processes such as cell growth, differentiation, apoptosis, metabolism and immune regulation (PubMed : 33633399). Key mediator of a quality checkpoint during transcription elongation as part of the Integrator-PP2A (INTAC) complex (PubMed : 33243860, PubMed : 34004147, PubMed : 37080207). The INTAC complex drives premature transcription termination of transcripts that are unfavorably configured for transcriptional elongation : within the INTAC complex, PPP2CA catalyzes dephosphorylation of the C-terminal domain (CTD) of Pol II subunit POLR2A/RPB1 and SUPT5H/SPT5, thereby preventing transcriptional elongation (PubMed : 33243860, PubMed : 34004147, PubMed : 37080207).
