Protein Name: Serine/threonine-protein phosphatase 2A catalytic subunit alpha isoform

UniprotKB/SwissProt ID: PP2AA_HUMAN (P67775)

Gene Name: PPP2CA

Organism: Homo sapiens (Human).

Function: PP2A is the major phosphatase for microtubule-associated proteins (MAPs). PP2A can modulate the activity of phosphorylase B kinase casein kinase 2, mitogen-stimulated S6 kinase, and MAP-2 kinase. Cooperates with SGOL2 to protect centromeric cohesin from separase-mediated cleavage in oocytes specifically during meiosis I (By similarity). Can dephosphorylate SV40 large T antigen and p53/TP53. Activates RAF1 by dephosphorylating it at 'Ser-259'.
