Activators are regulatory elements is not composed of DNA sequences.
In Eukaryotes transcriptional activators are composed of a DNA binding domain with a separated activation domain , These proteins also have a dimerization module.
Transcriptional activator is a protein that speeds transcription of a gene . Activators are the components that have positive control over gene expression, as they function to promote gene transcription. Their are several gene regulatory elements, including promoters, enhancers, silencers, and insulators . Regulatory Elements are Located in Promoter, Intergenic, and Intronic Regions.
