Acciones bioquímicas o fisiológicas

The transcription factor IIF (TFIIF) is composed of 58 kDa (RAP74) and 26 kDa (RAP30) subunits that form a heterodimer, and was first identified through the ability to interact with immobilized RNA polymerase II. In addition to its role in transcription initiation, TFIIF can increase the specificity and efficiency of RNA polymerase II transcription, and can especially increase the rate of transcription elongation.

Factors involved in specific transcription by mammalian RNA polymerase II. Factors IIE and IIF independently interact with RNA polymerase II.

O Flores et al.

The Journal of biological chemistry, 264(15), 8913-8921 (1989-05-25)

The purification and characterization of transcription factor IIF (TFIIF), a factor required for transcription by the RNA polymerase II machinery, is described. TFIIF was isolated from the previously described IIE protein fraction. TFIIF enters into the transcription cycle via a

Isolation of three proteins that bind to mammalian RNA polymerase II.

M Sopta et al.

The Journal of biological chemistry, 260(18), 10353-10360 (1985-08-25)

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
