Definition of circadian. : being, having, characterized by, or occurring in approximately 24-hour periods or cycles (as of biological activity or function) circadian rhythms in activity.
The circadian clock is the central timing system that controls numerous physiological processes. In mammals, one such process is haem biosynthesis, which the clock controls through regulation of the rate-limiting enzyme aminolevulinate synthase 1 (Alas1). Several members of the core clock mechanism are PAS domain proteins, one of which, neuronal PAS 2 (NPAS2), has a haem-binding motif.
