WebMay 19, 2024 · In addition to this core TTFL, CLOCK-BMAL1 also activates the transcription of the retinoic acid-related orphan nuclear receptors REV-ERB and ROR. REV–ERB and ROR competitively bind to retinoic acid-related orphan receptor response elements (ROREs) found in the BMAL1 promoter either to negate or promote transcription, respectively. WebOct 31, 2024 · The major clock genes involved in the TTFL include brain and muscle aryl hydrocarbon receptor nuclear translocator-like 1 (BMAL1), circadian locomotor output cycles kaput (CLOCK), period circadian regulator (PER)1/2, and cryptochrome circadian regulator (CRY)1/2, which form the main components of systems with a 24 h cycle.

WebA different approach to modulating the circadian clock is to target the repressive components of the core TTFL, which consists of the proteins CRY and PER . Inhibition of these proteins is predicted to prolong the transcriptional phase of the clock, whereas agonists would increase the length of the repressive phase.
