生化/生理作用
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.

RAP30/74 is a heteromeric general transcription initiation factor that binds to mammalian RNA polymerase II. The RAP30 subunit contains a region that is similar in amino acid sequence to the RNA polymerase-binding domain of the Escherichia coli transcription initiation factor

We have used affinity chromatography on columns containing immobilized calf thymus RNA polymerase II to isolate three phosphoproteins (RAP72, RAP38, and RAP30) that bind directly to RNA polymerase II. All could be isolated from cell nuclei, and all three could

RAP30/74 is a heteromeric general transcription initiation factor which binds to RNA polymerase II. Here we report that preparations of RAP30/74 contain an ATP-dependent DNA helicase whose probable function is to melt the DNA at transcriptional start sites. The sequence
