Enhancer At Biology Glossary

What is it? A cis-regulatory sequence that can elevate levels of transcription from an adjacent promoter. Many tissue specific enhancers can determine spatial patterns of gene expression in higher eukaryotes. Enhancers can act on promoters over many tens of kilobases of DNA and can be 5 or 3 to the promoter they regulate. A eukaryotic DNA sequence that increases transcription of a region even if the enhancer is distant from the region being transcribed.
