The mammalian circadian clock requires the master transcription factors CLOCK and BMAL1 to drive rhythmic gene expression. Here, Menet et al. report that rhythmic binding of CLOCK:BMAL1 on DNA promotes rhythmic chromatin opening. Mechanisms include CLOCK:BMAL1 binding to nucleosomes and chromatin modifications such as incorporation of histone variant H2A.Z. The data indicate that clock regulation of transcription relies on rhythmic regulation of chromatin accessibility, thus extending the concept of pioneer factor function to acute gene regulation. The mammalian circadian clock relies on the master genes CLOCK and BMAL1 to drive rhythmic gene expression and regulate biological functions under circadian control. Here we show that rhythmic CLOCK:BMAL1 DNA binding promotes rhythmic chromatin opening. Mechanisms include CLOCK:BMAL1 binding to nucleosomes and rhythmic chromatin modification; e.g., incorporation of the histone variant H2A.Z. This rhythmic chromatin remodeling mediates the rhythmic binding of other transcription factors adjacent to CLOCK:BMAL1, suggesting that the activity of these other transcription factors contributes to the genome-wide CLOCK:BMAL1 heterogeneous transcriptional output. These data therefore indicate that the clock regulation of transcription relies on the rhythmic regulation of chromatin accessibility and suggest that the concept of pioneer function extends to acute gene regulation.
