About PPP2R1B

Cytogenetic location: 11q23.1 Genomic coordinates (GRCh38): 11:111,688,000-111,766,389 (from NCBI)

This gene has 12 transcripts (splice variants), 192 orthologues, 2 paralogues and is associated with 1 phenotype. Ubiquitous expression in testis (RPKM 13.7), fat (RPKM 13.4) and 25 other tissues.

Summary

This gene 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. This gene encodes a beta isoform of the constant regulatory subunit A. Mutations in this gene have been associated with some lung and colon cancers. Alternatively spliced transcript variants have been described. [provided by RefSeq, Apr 2010]
