Protein
Major serine/threonine-protein phosphatase PP2A-2 catalytic subunit
Gene
ppa2, SPBC16H5.07c
Organism
Schizosaccharomyces pombe (strain 972 / ATCC 24843) (Fission yeast)
Status
Reviewed - Annotation score: 5 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.
