Coactivation is a process by which the transcription of RNA is increased. Proteins called coactivators are recruited to DNA-binding transcription factors through their activation domains and increase transcription by relaxing the chromatin structure to allow greater access to a gene or by bringing in components of the basal transcription complex needed for transcription to occur. Examples of coactivators are CBP, p300, and SWI/SNF.^[1]
