Enhancers

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

Enhancers are regulatory DNA sequences of gene expression that augment the activity of a promoter in an orientation-, position-, and distance-independent manner. These sequences play a key role in the regulation of tissue-specific gene expression in higher eukaryotes. Classically, trans-acting gene regulatory proteins are thought to bind to enhancers in order to impact transcriptional activity of their associated promoters. However, more recently, evidence has emerged that points to other diverse mechanisms by which enhancers may exert their effects on gene expression, including through epigenetic modifications, alterations of chromatin structure, and noncoding RNAs.
