Hikari Yoshitane, Yoshimasa Asano et al. investigate role of the D-box genomic element in the circadian clockwork and identify 1490 D-box-containing regions that are bound by DBP and E4BP4 in the mouse liver. Using mice lacking liver expression of E4bp4, they demonstrate the importance of the D-box element for mediating environmental input response and resetting the circadian clock.
