Serine/threonine-protein phosphatase 2A catalytic subunit beta isoform is an enzyme that in humans is encoded by the PPP2CB gene.[5]

Function

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. Two transcript variants encoding the same protein have been identified for this gene.[6]

Interactions

PPP2CB has been shown to interact with TLX1,[7] PPP2R1B[8] and PPP2R1A.[8][9]
