[5] 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.
