The circadian transcription factors BMAL1:CLOCK bind to E/E′-boxes in gene regulatory elements of their targets and facilitate rhythmic expression. Here, the authors mutate the Per2 promoter E’′-box in mice and observe that cell- and tissue-autonomous oscillations are dampened and that animals are less susceptible to jet lag.
