Description
Summary from GEO:

"Nuclear-receptor-binding SET-domain protein 1 (NSD1), a methyltransferase that catalyzes H3K36me2, is essential for mammalian development and frequently dysregulated in diseases, including Sotos syndrome. Despite impacts of H3K36me2 on H3K27me3 and DNA methylation, a direct role of NSD1 in transcriptional regulation remains largely unknown. Here, we show that NSD1 and H3K36me2 are enriched at cis-regulatory elements, particularly enhancers. NSD1 enhancer association is conferred by a tandem quadruple PHD-PWWP module, which recognizes p300-catalyzed H3K18ac. By combining acute NSD1 depletion with time-resolved epigenomic and nascent transcriptomic analyses, we demonstrate that NSD1 promotes enhancer-dependent gene transcription by facilitating RNA polymerase II pause release. Notably, NSD1 can act as a transcriptional coactivator independent of its catalytic activity. Moreover, NSD1 enables activation of developmental transcriptional programs associated with Sotos syndrome pathophysiology and controls ESC multilineage differentiation. Collectively, we have identified NSD1 as an enhancer-acting transcriptional coactivator that contributes to cell fate transition and Sotos syndrome development."

Overall design from GEO:

"RNA-seq was performed with wild-type mESCs nontreated or treated with 500 nM dTAG-13 for 72h. RNA-seq was also performed with nontreated NSD1-dTAG mESCs and embryoid bodies (EBs) differentiated for 6 days from NSD1-dTAG mESCs in the presence or absence of 500 nM dTAG-13."
