PP2A-ABeta Polyclonal Antibody

PPP2R1B encodes a constant regulatory subunit of protein phosphatase 2. Protein phosphatase 2 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. The constant regulatory subunit A serves as a scaffolding molecule to coordinate the assembly of the catalytic subunit and a variable regulatory B subunit. PPP2R1B encodes a beta isoform of the constant regulatory subunit A. Mutations in PPP2R1B have been associated with some lung and colon cancers. Alternatively spliced transcript variants have been described.
