(Submitter supplied) Histone H2B was mutated to give H2B^3-32, H2B K->G, H2B^3-37, and H2B^30-37. Total RNA from three replicate cultures of wild-type and mutant was isolated and the expression profiles were determined using Affymetrix arrays. Comparisons between the sample groups allow the identification of genes regulated by H2B HBR domain. This SuperSeries is composed of the SubSeries listed below.

(Submitter supplied) 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.

(Submitter supplied) Evidence suggests that the TAF1 subunit of TFIID is a histone acetyltransferase (HAT) that is functionally redundant with the Gcn5 HAT of the SAGA and ADA complexes. Here we test a number of predictions of this hypothesis by examining the in vivo histone acetylation targets of TAF1 and Gcn5, and re-examining the basis for the reported genome-wide functional redundancy between TAF1 and Gcn5. Our findings do not support a number of basic tenets of the hypothesis, thus bringing into question the physiological presence of any TAF1 HAT function in yeast. more...

(Submitter supplied) In budding yeast, telomeres and the mating type (HM) loci are found in a heterochromatin-like silent structure initiated by Rap1 and extended by the interaction of Sir (Silencing Information Regulator) proteins with histones. Binding data demonstrate that both the H3 and H4 N terminal domains required for silencing in vivo interact directly with Sir3 and Sir4 in vitro. The role of H4 lysine 16 deacetylation is well established in Sir3 protein recruitment, however that of the H3 N terminal tail has remained unclear. more...
