Biochem/physiol Actions GSK4112 is a rev-erbα, (orphan nuclear receptor NR1D1) agonist, the first agent able to reset the circadian clock in a phase-dependent manner. Rev-erbα impacts the precision of the circadian clock by repressing target gene activities with the help of a nuclear receptor co-repressor complex (NCoR) and HDAC3. GSK4112 competes with heme (rev-erb′s natural ligand) and enhances co-repressor complex recruitment and thus, repression of transcription. suggests that pharmacological modulation through Rev-erb may provide new routes to treat metabolic diseases, especially disorders of adipogenesis regulated by rev-erba.1 |
