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].

The general transcription factor TFIIE has an essential role in eukaryotic transcription initiation together with RNA polymerase II and other general factors. Human TFIIE consists of two subunits TFIIE-alpha Swiss:P29083 and TFIIE-beta Swiss:P29084 and joins the pre-initiation complex after RNA polymerase II and TFIIF [1]. This family consists of the conserved amino terminal region of eukaryotic TFIIE-alpha [2] and proteins from archaebacteria that are presumed to be TFIIE-alpha subunits also Swiss:O29501 [3].
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].
