Biochem/physiol Actions
The transcription factor IIF (TFIIF) is composed of 58 kDa (RAP74) and 26 kDa (RAP30) subunits as a heterodimer, and was first identified through the ability to interact with immobilized RNA polymerase II. The RAP30 subunit of TFIIF contains two distinct regions with sequence similarity to E coli factors and can deliver RNA polymerase II to the promoter to support transcription initiation in the absence of RAP74.
