Figure 1. Comparison of human retinoic acid receptor-related orphan receptors and REV-ERB nuclear hormone receptors.
(A) The numbers indicate amino acid identity relative to RORα. RORα4, RORβ1 and RORγ1 are shown. (B) The numbers indicate amino acid identity relative to REV-ERBα. AF: Activation-function; DBD: DNA-binding domain; LBD: Ligand-binding domain; ROR: Retinoic acid receptor-related orphan receptor.
