Background Information

The PPP2R2B gene encodes a deduced 443-amino acid protein of approximately 52 kDa,which is a brain-specific regulatory subunit B of protein phosphatase 2. PPP2R2B is a Subunit of PP2A, a highly conserved constitutive enzyme(PMID:11719278). PPP2R2B (Bβ) is an important regulator of protein phosphatase 2A (PP2A) activity in the brain. Through differential promoter usage and alternative splicing, two major isoforms Bβ1 and Bβ2 with divergent sub-cellular targeting N termini are produced. Bβ plays an important role in neuronal survival. It has 5 isoforms produced by alternative splicing. This antibody has cross-reactivity to PPP2R2A, PPP2R2C and PPP2R2D.
