RARB iso2 is a receptor for retinoic acid, a potent mammalian morphogen and teratogen that has profound effects on vertebrate development. RARB is a member of the nuclear receptor superfamily. Controls cell function by directly regulating gene expression. Composed of three domains: a modulating N-terminal domain, a DNA-binding domain and a C-terminal steroid-binding domain. Four splice-variant isoforms have been described. Isoform beta-1 and beta-2 are nuclear and isoform beta-4 cytoplasmic. Note: This description may include information from UniProtKB.
