Facts about Serine/threonine-protein phosphatase 2A catalytic subunit alpha isoform.
Cooperates with SGO2 to protect centromeric cohesin from separase-mediated cleavage in oocytes especially during meiosis I (By similarity). Can dephosphorylate SV40 large T antigen and p53/TP53.

Cytoplasm. Nucleus. Chromosome, centromere. Cytoplasm, cytoskeleton, spindle pole. In prometaphase cells, but not in anaphase cells, localizes at centromeres. During mitosis, also found at spindle poles. Centromeric localization requires the presence of SGO2 (By similarity).
