Chip-seq enhancer
WebMar 24, 2014 · Currently, enhancers can be identified through chromatin-based assays, such as ChIP-seq, which predict enhancer elements indirectly based on the enhancer’s association with specific epigenomic marks, such as transcription factors or molecular tags on DNA-associated histone proteins. Visel, Pennacchio, Dickel and their colleagues … WebJul 16, 2024 · Super-enhancers are typically an order of magnitude larger than typical enhancers in size, have higher transcription factor density, and greater ability for transcriptional activation. b Enhancers are plotted in increasing order based on ChIP-Seq peak intensity. Super-enhancers are the population above the inflection point of the curve

WebSuper-enhancers¶. An enhancer is a short (50-1500 bp) region of DNA that can be bound by proteins (activators) to increase the likelihood transcription will occur at a gene. They can be located up to 1 Mbp (1,000,000 bp) away from the gene, either upstream or downstream from the start site, and either in the forward or backward direction.
