Rarb Gene Summary [Rat]
Enables heterocyclic compound binding activity and nuclear retinoid X receptor binding activity. Involved in neural precursor cell proliferation and regulation of myelination. Predicted to be located in nucleoplasm. Human ortholog(s) of this gene implicated in asbestos-related lung carcinoma; lung adenocarcinoma; lung non-small cell carcinoma; lung small cell carcinoma; and syndromic microphthalmia 12. Orthologous to human RARB (retinoic acid receptor beta). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Rarb often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
