[[http://www.uniprot.org/uniprot/2AAA_HUMAN 2AAA_HUMAN]] The PR65 subunit of protein phosphatase 2A serves as a scaffolding molecule to coordinate the assembly of the catalytic subunit and a variable regulatory B subunit. Required for proper chromosome segregation and for centromeric localization of SGOL1 in mitosis.<ref>PMID:16580887</ref> [[http://www.uniprot.org/uniprot/PP2AA_HUMAN PP2AA_HUMAN]] 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'.<ref>PMID:9920888</ref> <ref>PMID:10801873</ref> <ref>PMID:22613722</ref>
