Shadow enhancers regulate a common target gene and drive expression patterns that overlap spatiotemporally. The authors review recent insights into the prevalence and role of shadow enhancers in metazoans, as well as their mechanisms of action to fine-tune gene expression. They also discuss the evolution of shadow enhancers and their implication in disease.
