Protein
Minor serine/threonine-protein phosphatase PP2A-1 catalytic subunit
Gene
ppa1, SPAC823.15
Organism
Schizosaccharomyces pombe (strain 972 / ATCC 24843) (Fission yeast)
Status
Reviewed - Annotation score: 4 out of 5 - Protein inferred from homologyi

Functioni

Essential role in cell cycle control. PP2A may be involved in controlling the entry into mitosis, possibly acting as an inhibitor.

Catalytic activityi

[a protein]-serine/threonine phosphate + H2O = [a protein]-serine/threonine + phosphate.

Cofactori

Binds 2 manganese ions per subunit By similarity.
