Mammalian PERIOD2 regulates H2A.Z incorporation into chromatin to orchestrate circadian negative feedback [RNA-Seq]

We report the interdependance of PERIOD and H2A.Z to orchestrated the circadian negative feedback. H2A.Z is required for the circadian rhythm, it allows the binding of Bmal1 and PERIOD2 to the chromatin. And reciprocally, PERIOD2 aid H2A.Z deposition by interacting with the specific chaperone YL1.
