Transcriptional activators and activation mechanisms

Jun Ma 1,
PMCID: PMC4712173  PMID: 22180087

Abstract

Transcriptional activators are required to turn on the expression of genes in a eukaryotic cell. Activators bound to the enhancer can facilitate either the recruitment of RNA polymerase II to the promoter or its elongation. This article examines a few selected issues in understanding activator functions and activation mechanisms.

Keywords: activator, transcription, co-activator, enhancer, promoter, signal transduction, development
