A different twist on centromeric chromatin

Abstract

Nucleosomes at the centromere contain CENP-A, a histone H3 variant that establishes a specific, yet poorly defined centromeric chromatin architecture. In this issue of Structure, Takizawa et al. (2019) describe an untwisted configuration for an H3-CENP-A-H3 tri-nucleosome that mimics centromeric chromatin. Untwisting may increase centromeric-protein accessibility to CENP-A in compacted chromatin.
