CC -!- FUNCTION: Essential role in cell cycle control. PP2A may be involved in
CC controlling the entry into mitosis, possibly acting as an inhibitor.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + O-phospho-L-seryl-[protein] = L-seryl-[protein] +
CC phosphate; Xref=Rhea:RHEA:20629, Rhea:RHEA-COMP:9863, Rhea:RHEA-

CC COMP:11605, ChEBI:CHEBI:15377, ChEBI:CHEBI:30013, ChEBI:CHEBI:43474,
CC ChEBI:CHEBI:61977; EC=3.1.3.16;
CC -!- COFACTOR:
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035; Evidence={ECO:0000250};
CC Note=Binds 2 manganese ions per subunit. {ECO:0000250};
CC -!- MISCELLANEOUS: Retarded cell growth is produced by disruption of ppa2.
CC -!- SIMILARITY: Belongs to the PPP phosphatase family. PP-2A subfamily.
CC {ECO:0000305}.
