WebJan 1, 2024 · The mammalian circadian clock at the molecular level is composed of a time-delayed transcription-translation feedback loop (TTFL) (5–8). BMAL1 and CLOCK (or its paralog NPAS2) make up the activator arm, and cryptochrome (CRY1 and CRY2) and PER (PER1, PER2, and likely PER3) proteins constitute the repressor arm of the TTFL (9, 10). WebJan 1, 2024 · The TTFL of mammals involves transcriptional activation by Clock/Bmal1 hetero-dimers, which drive daytime expression of Period (Per) and Cryptochrome (Cry) genes through E-box regulatory sequences.
