Retinoid X receptor beta (RXR-beta), also known as NR2B2 (nuclear receptor subfamily 2, group B, member 2) is a nuclear receptor that in humans is encoded by the ''RXRB'' gene. This gene encodes a member of the

retinoid X receptor The retinoid X receptor (RXR) is a type of nuclear receptor that is activated by 9-cis retinoic acid, which is discussed controversially to be of endogenous relevance, and 9-''cis''-13,14-dihydroretinoic acid, which is likely to be the major e ...

retinoic acid Retinoic acid (used simplified here for all-''trans''-retinoic acid) is a metabolite of vitamin A1 (all-''trans''-retinol) that mediates the functions of vitamin A1 required for growth and development. All-''trans''-retinoic acid is required in ...

alternatively spliced Alternative splicing, or alternative RNA splicing, or differential splicing, is an alternative splicing process during gene expression that allows a single gene to code for multiple proteins. In this process, particular exons of a gene may be ...

transcript variant has been described, but its full length sequence has not been determined.
