Transcription-dependent targeting of Hda1C to hyperactive genes mediates H4-specific deacetylation in yeast (RNA-seq)
Hda1C directly binds to actively transcribed regions likely via the interaction with elongating RNA PolII and/or with nascent RNA transcripts. The Arb2 domain of Hda1 is also critical for its binding to chromatin. Interestingly, Hda1C specifically deacetylates histone H4 but not H3 at active genes to suppress nucleosome instability and partially inhibit elongation. In contrast, Hda1C mainly deacetylates histone H3 at inactive genes to delay gene induction. Overall design: The examination of the changes of gene expression during carbon source shifts.
