Transcription initiation factor IIA, gamma subunit, helical domain Accurate transcription in vivo requires at least six general transcription initiation factors, in addition to RNA polymerase II. Transcription initiation factor IIA (TFIIA) is a multimeric protein which facilitates the binding of TFIID to the TATA box. The N-terminal domain of the gamma subunit is a 4 helix bundle. |
