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 a beta isoform of the catalytic subunit. [provided by RefSeq, Mar 2010]

A study in rats demonstrated that the PPP2CB (Ppp2cb) is a negative regulator of RAS-RAC signaling, which down-regulates RAS-induced activation of NF-kB pathways, providing a late-stage mechanism to prevent chronic inflammation following thermal injury [Yang et al. DOI:10.1186/1471-2105-8-10].
