WebMar 18, 2024 · The transcription factors that bind to the enhancers and activate the gene expression are known as activators. They help basal transcription factors and/or RNA polymerase to bind to the promoter. … WebA typical transcription factor binds to DNA at a certain target sequence. Once it's bound, the transcription factor makes it either harder or easier for RNA polymerase to bind to the promoter of the gene. Activators Some transcription factors activate transcription.
WebMar 29, 2024 · A good correlation is, rather, found with binding of immunopurified holo-TFIID to this element. TFIID interacts both with Ea TATA-like and Inr sequences, but only the latter is functionally relevant. Unlike TBP, TFIID binds in the absence of TFIIA, indicating a stabilizing role for TBP-associated factors in Ea promoter recognition. WebSee Page 1.
