Serine/threonine-protein phosphatase 2A catalytic subunit alpha isoform is an enzyme that (in humans) is encoded by the PPP2CA gene.[5]

Function[edit]

This gene encodes the phosphatase 2A catalytic subunit. Protein phosphatase 2A is one of the four major Ser/Thr phosphatases, and it is implicated in the negative control of cell growth and division. It consists of a common heteromeric core enzyme, which is composed of a catalytic subunit and a constant regulatory subunit, that associates with a variety of regulatory subunits. This gene encodes an alpha isoform of the catalytic subunit.[6]

Interactions[edit]

PPP2CA has been shown to interact with:
