Factors Involved in Specific Transcription by Mammalian RNA Polymerase II

Open access

Abstract

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 preinitiation complex, and it is required for the formation of a complex capable of initiating transcription in the presence of heparin concentrations that inhibit the action of a free factor. TFIIF and TFIIE independently interacted with purified RNA polymerase II. TFIIF and TFIIE were both required for transcription of several class II promoters, including a promoter that lacks the conserved TATA box. Interestingly TFIIF was absolutely required for the formation of a preinitiation complex; however, it also affected the elongation phase of the transcription cycle. TFIIF, together with the previously described elongation factor TFIIS, was required for efficient elongation.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
