Difference between promoter and enhancer
WebTo capture the enhancer-gene pair as a unit, rather than just the enhancer or just the gene, we also defined new features consisting of interaction terms between the enhancer-specific features and the promoter-specific features (Table (Table3). 3). This resulted in up to 17 total features for each dataset of cell type-specific enhancer-gene pairs. WebMetazoan enhancers can be megabases distant from the core promoters they regulate, 26 and the spatial relationship of enhancers and promoters is an additional layer of complexity. 27, 28 The yeast genome is an ideal context to study the functional connection between distal and core promoter elements, as long-distance regulation of core ...
