Figure 1. Structure of the RORs and REV-ERBs.
a | The general organizational structure of members of the nuclear receptor superfamily. b | Structure of the REV-ERBs. c | Structure of the retinoic acid receptor-related orphan receptors (RORs). Numbers above each receptor represent the amino acid position. Percentages indicate amino acid identity within a particular domain relative to either REV-ERBα or RORα. A/B, C, D, E and F refer to classically defined regions in the nuclear receptor domain structure. DBD, DNA-binding domain; LBD, ligand-binding domain.
