BMAL1 a transcriptional activator protein that forms a core component of the circadian clock. An aryl hydrocarbon receptor nuclear translocator-like protein. A circadian regulatory protein and substrate of casein kinase I epsilon. The circadian clock, an internal time-keeping system, regulates various physiological processes through the generation of approximately 24 hour circadian rhythms in gene expression, which are translated into rhythms in metabolism and behavior. Heterodimers bind to an E-box element (3'-CACGTG-5'), thereby activating transcription of PER1, and possibly of other circadian clock proteins. Nine splice isoforms have been reported.
