Collaborative repressive action of the antagonistic ETS transcription factors Pointed and Yan fine-tunes gene expression to confer robustness in Drosophila.

Project description:The acquisition of cellular identity during development depends on precise spatiotemporal regulation of gene expression, with combinatorial interactions between transcription factors, accessory proteins and the basal transcription machinery together translating complex signaling inputs into appropriate gene expression outputs. The opposing repressive and activating inputs of the Drosophila ETS family transcription factors Yan and Pointed orchestrate numerous cell fate transitions downstream of receptor tyrosine kinase signaling, providing one of the premier systems for studying this process. Current models describe the differentiative transition as a switch from Yan-mediated repression to Pointed-mediated activation of common target genes. We describe here a new layer of regulation whereby Yan and Pointed co-occupy regulatory elements to repress gene expression in a coordinated manner, with Pointed being unexpectedly required for the genome-wide occupancy of both Yan and the co-repressor Groucho. Using even skipped as a test-case, synergistic genetic interactions between Pointed, Groucho, Yan and components of the RNA polymerase II pausing machinery suggest that Pointed integrates multiple scales of repressive regulation to confer robustness. We speculate that this mechanism may be used broadly to fine-tune the expression of many genes crucial for development.

Genome-Wide Yan Chromatin Occupancy in Drosophila Embryos

Project description:The ETS transcriptional repressor Yan functions as part of a developmental switch that in response to receptor tyrosine kinase signaling, transitions from a high-Yan to a low-Yan state to direct specification of a variety of cell fates. To date very few direct target genes have been identified, nor is it clear how their expression is buffered against developmental noise to prevent inappropriate oscillations between states. Following investigation of its genome-wide chromatin occupancy profile, we noticed a striking signature at developmentally important genes whereby Yan associates with chromatin in regions of high-peak density that span multiple kilobases which partially relies upon SAM-domain mediated self-association. We speculate that the high-density Yan occupancy signature may reveal a novel mechanism that buffers the expression of critical developmental regulators against intrinsic and environmental noise.
