چکیده

Watanabe et al (Reports, 12 April 2013, p. 195) study the yeast SWR1/SWR-C complex responsible for depositing the histone variant H2A.Z by replacing nucleosomal H2A with H2A.Z. They report that reversal of H2A.Z replacement is mediated by SWR1 and related INO80 on an H2A.Z nucleosome carrying H3K56Q. Using multiple assays and reaction conditions, we find no evidence of such reversal of H2A.Z exchange.

NuA4-directed chromatin transactions throughout the Saccharomyces cerevisiae genome.

Two of the major histone acetyltransferases in Saccharomyces cerevisiae are NuA4 and SAGA, which acetylate histones H4 and H3, respectively. Acetylated H3 and H4 tails have been implicated in binding bromodomain proteins, including Bdf1. Bdf1 interacts with the general transcription factor TFIID, which might promote preinitiation complex (PIC) assembly. Bdf1 also interacts with the SWR complex ...

Dual function of Swc5 in SWR remodeling ATPase activation and histone H2A eviction

The chromatin remodeler SWR deposits histone H2A.Z at promoters and other regulatory sites via an ATP-driven histone exchange reaction that replaces nucleosomal H2A with H2A.Z. Simultaneous binding of SWR to both H2A nucleosome and free H2A.Z induces SWR ATPase activity and engages the histone exchange mechanism. Swc5 is a conserved subunit of the 14-polypeptide SWR complex that is required for...

SWR-C and INO80 Chromatin Remodelers Recognize Nucleosome-free Regions Near +1 Nucleosomes

SWR-C/SWR1 and INO80 are multisubunit complexes that catalyze the deposition and removal, respectively, of histone variant H2A.Z from the first nucleosome at the start of genes. How they target and engage these +1 nucleosomes is unclear. Using ChIP-exo, we identified the subnucleosomal placement of 20 of their subunits across the yeast genome. The Swc2 subunit of SWR-C bound a narrowly defined ...

Asf1-like structure of the conserved Yaf9 YEATS domain and role in H2A.Z deposition and acetylation.

Chromatin can be modified by posttranslational modifications of histones, ATP-dependent remodeling, and incorporation of histone variants. The Saccharomyces cerevisiae protein Yaf9 is a subunit of both the essential histone acetyltransferase complex NuA4 and the ATP-dependent chromatin remodeling complex SWR1-C, which deposits histone variant H2A.Z into euchromatin. Yaf9 contains a YEATS domain...
