The transcription factor TFIIB contains a zinc-binding motif near the N-terminus. This domain is involved in the interaction with RNA pol II and TFIIF and plays a crucial role in selecting the transcription initiation site. The domain adopts a zinc ribbon like structure [1].
This is the second winged helix domain can be found in TFA2 proteins present in Saccharomyces cerevisiae. In form 2, the domain interacts directly with Rad3, a DNA helicase [1].
General transcription factor TFIIE consists of two subunits, TFIIE alpha Pfam:PF02002 and TFIIE beta. TFIIE beta has been found to bind to the region where the promoter starts to open to be single-stranded upon transcription initiation by RNA polymer ...
General transcription factor TFIIE consists of two subunits, TFIIE alpha Pfam:PF02002 and TFIIE beta. TFIIE beta has been found to bind to the region where the promoter starts to open to be single-stranded upon transcription initiation by RNA polymerase II. The structure of the DNA binding core region has been solved [1] and has a winged helix fold.
