Rev-ErbA beta (Rev-erbβ) also known as NR1D2 (nuclear receptor subfamily 1, group D, member 2) is a member of the Rev-ErbA family of transcription factors. Rev-erbβ, like Rev-erbα, belongs to the nuclear receptor superfamily and can modulate gene expression by directly binding to their promoters.

Rev-erbβ is similar to Rev-erbα in its protein structure and function as a transcriptional repressor. The crystal structure of the Rev-erbβ ligand-binding domain (LBD) has been resolved and shows an extremely small ligand-binding pocket, though it is possible that ligands can bind in a non-canonical fashion. Indeed, Rev-erbβ has been shown to interact with heme, which may be important for its function.

Rev-erbβ is also a circadian regulated gene; its mRNA displays rhythmic expression in vivo and in serum-synchronized cell cultures. However, it is currently unknown to what extent Rev-erbβ contributes to oscillations of the core circadian clock.
