Transcription initiation factor TFIID subunit 9B is a protein that in humans is encoded by the TAF9B gene.Initiation of transcription by RNA polymerase II requires the activities of more than 70 polypeptides. The protein that coordinates these activities is transcription factor IID (TFIID) which binds to the core promoter to position the polymerase properly serves as the scaffold for assembly of the remainder of the transcription complex and acts as a channel for regulatory signals.
