Claim: The product of PPP232B belongs to the family of protein phosphatase 2, which is implicated in the negative control of cell growth and division, and consists of a common heteromeric core enzyme, and defects in this gene may cause a rare form of  of autosomal dominant spinocerebellar ataxia 12.
Evidence: The product of this gene belongs to the phosphatase 2regulatory subunit B family. 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. Defects in the 5' UTR of this gene may cause a rare form of autosomal dominant spinocerebellar ataxia 12.
