1
It is a component of transcription factor TFIID.
2
TBP recognizes the TATA element by inserting one of its α-helices into the major groove of B-DNA.
3
The TBP-DNA interaction causes the DNA to bend.
4
The TBP-DNA interaction is governed in part by the intercalation of the side chains of phenylalanine residues of TBP between the base pairs at the two ends of the TATA element sequence.
