PPP2R2B

Protein phosphatase 2 (formerly 2A), regulatory subunit B, beta isoform, also known as PPP2R2B, is a human gene.

PBB_Summary
section_title =
summary_text = The product of this gene belongs to the phosphatase 2 regulatory 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. The B regulatory subunit might modulate substrate selectivity and catalytic activity. This gene encodes a beta isoform of the regulatory subunit B55 subfamily. Defects in the 5' UTR of this gene may cause a rare form of autosomal dominant spinocerebellar ataxia 12.cite web | title = Entrez Gene: PPP2R2B protein phosphatase 2 (formerly 2A), regulatory subunit B, beta isoform| url = http://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=5521| accessdate = ]
