RARB (Retinoic Acid Receptor Beta): RARB is a nuclear receptor that binds retinoic acid, a metabolite of vitamin A. It plays a key role in regulating gene expression during development, especially in epithelial tissue growth, cell differentiation, and nervous system formation. Altered RARB activity has been associated with cancers such as skin, lung, and breast, as well as developmental disorders, and is under investigation for potential retinoid-based therapies.
