Initiation of transcription by RNA polymerase II requires the activities of more than 70 polypeptides. The protein thatcoordinates these activities is transcription factor IID (TFIID), which binds to the core promoter to position thepolymerase properly, serves as the scaffold for assembly of the remainder of the transcription complex, and acts as achannel for regulatory signals. TFIID is composed of the TATA-binding protein (TBP) and a group of evolutionarilyconserved proteins known as ...
