(Submitter supplied) In D. melanogaster males, X chromosome monosomy is compensated by chromosome-wide transcription activation. We found that complete dosage compensation during embryogenesis takes surprisingly long. Although the activating Dosage Compensation Complex (DCC) associates with the chromosome and acetylates histone H4 early, many genes are not compensated. Acetylation levels on gene bodies continue to increase for several hours after gastrulation in parallel with progressive compensation. more...

(Submitter supplied) Before zygotic genome activation (ZGA) the quiescent genome undergoes reprogramming to transition into the transcriptionally active state. However, the mechanisms underlying euchromatin establishment during early embryogenesis remain poorly understood. Here, we show that histone H4 lysine-16 acetylation (H4K16ac) is maintained from oocytes to fertilized embryos in Drosophila and mammals. H4K16ac forms large domains that control nucleosome accessibility of promoters prior to ZGA in flies. more...

(Submitter supplied) We have systematically studied the contribution of the histone acetyltransferase MOF for Drosophila embryos development characterizing the expression changes at st5, st7 and st15 in male and female embryos. Additionally, we studied the contribution of the histone acetyltransferase MOF for the transcription of male S2 cells.

(Submitter supplied) Drosophila MSL complex binds the single male X chromosome to upregulate gene expression to equal that from the two female X chromosomes. However, it has been puzzling that ~25% of transcribed genes on the X do not stably recruit MSL complex. Here, we find that almost all active genes on the X are associated with robust H4 Lys16 acetylation (H4K16ac), the histone modification catalyzed by MSL complex. more...

(Submitter supplied) The H4K16 acetyltransferase MOF plays a crucial role in dosage compensation in Drosophila, but has additional, global functions in gene control. We compared the molecular context and effect of MOF activity in male and female flies combining chromosome-wide mapping and transcriptome studies with analyses of defined reporter loci in transgenic flies. MOF distributes dynamically between two types of complexes, the Dosage Compensation Complex (DCC) and complexes containing MBD-R2, a global facilitator of transcription. more...

(Submitter supplied) MSL (Male-specific lethal) complex increases transcription on the single X chromosome of Drosophila males in order to equalize expression of X-linked genes between males (XY) and females (XX). The increase in transcript levels correlates with MSL- dependent acetylation of histone H4 at K16 within the bodies of active genes, but identification of the transcriptional step affected has not been possible. more...

(Submitter supplied) The Drosophila MSL complex mediates dosage compensation by increasing transcription of the single X chromosome in males approximately two-fold. This is accomplished through recognition of the X chromosome and subsequent acetylation of histone H4K16 on X-linked genes. Initial binding to the X is thought to occur at a subset of sites. However, the consensus sequence motif of entry sites (“MSL recognition element” or MRE) is only slightly enriched on the X (~2 fold), and only a fraction of them is utilized by the MSL complex. more...
