Rabbit polyclonal antibody to RORγ

The nuclear orphan receptors RORα and RORg are members of the nuclear hormone receptor superfamily. Members of this family acts by directly associating with DNA sequences known as hormone response elements (HREs) and typically bind DNA as either homo~ or heterodimers. RORα and RORg are unique in that they bind DNA as monomers. RORα has multiple isoforms that share common DNA and putative ligand~binding domains, but differ in their amino terminal domains, which are generated by alternative RNA processing. RORg comprises a 560 amino acid protein that shares 50% amino acid identity with RORα and is most highly expressed in skeletal muscle. Although these proteins are considered “orphan receptors,” due to a lack of defined ligands, experimental evidence has shown that melatonin may be the natural ligand for these nuclear receptors. The gene encoding RORα maps to chromosome 15q22.2 and the gene encoding RORg maps to chromosome 1q21.3.
