Multiple roles of H2A.Z in regulating promoter chromatin architecture in human cells

Abstract

Histone variant H2A.Z has been suggested to contribute to the regulation of promoter accessibility. Here, the authors present high-depth maps of the position and accessibility of H2A.Z-containing nucleosomes for human Pol II promoters and provide evidence that H2A.Z has multiple and distinct roles in regulating gene expression dependent upon its location in a promoter.
