Project description:Although the conserved AAA ATPase â bromodomain factor, ATAD2, has been described as a transcriptional co-activator upregulated in many cancers, its function remains poorly understood. Here, using a combination of ChIP-seq, ChIP-proteomics and RNA-seq experiments in embryonic stem cells, we found that Atad2 is an abundant nucleosome-bound protein present on active genes, associated with chromatin remodelling, DNA replication and DNA repair factors. A structural analysis of its bromodomain and subsequent investigations demonstrate that histone acetylation guides ATAD2 to chromatin, resulting in an overall increase of chromatin accessibility and histone dynamics, which is required for the proper activity of the highly expressed gene fraction of the genome. While in exponentially growing cells Atad2 appears dispensable for cell growth, in differentiating ES cells, Atad2 becomes critical in sustaining specific gene expression programs, controlling proliferation and differentiation. Altogether, this work defines Atad2âs function as a facilitator of general chromatin-templated activities such as transcription. Transcriptomic analyses comparing ES cells stably expressing anti-Atad2 shRNA versus cells expressing control shRNA, in day 3 LIF (-) differentiating ES cells (3 replicates for each condition) were performed using the Illumina MouseWG-6 v2.0 expression beadchip technology

Project description:A functional cooperation between an AAA type ATPase domain and a bromodomain has been evidenced. These two domains were identified and their activity tested in a yet uncharacterized factor, named Atad2, whose two-domain configuration remained highly conserved during evolution. In human and mouse, Atad2 is most abundantly expressed in testis and in the mouse. It has also been detected in post-meiotic stages and in mature spermatozoa. The AAA-ATPase domain was found necessary for protein multimerization and high affinity binding to acetylated nucleosomes by its bromodomain. The binding was found specific to acetylated histone H4 tail with a critical role for the acetylated K5 position. In vivo studies show that Atad2 behaves as a general repressor of transcription and possesses a chromatin “freezing” activity. Finally, we demonstrate that the induction of apoptosis leads to an early degradation of Atad2, which probably facilitates the action of apoptotic factors by increasing chromatin dynamics.
