Binding of TFIID to the TATA box is the initial transcriptional step of the pre-initiation complex (PIC), playing a role in the activation of eukaryotic genes transcribed by RNA polymerase II. Publication Abstract from PubMed The three-dimensional structure of a TATA box-binding protein (TBP) from Arabidopsis thaliana complexed with a fourteen base pair oligonucleotide bearing the Adenovirus major late promoter TATA element has been refined at 1.9 A resolution, giving a final crystallographic R-factor of 19.4%. Binding of the monomeric, saddle-shaped alpha/beta protein induces an unprecedented conformational change in the DNA. A detailed structural and functional analysis of this unusual protein-DNA complex is presented, with particular emphasis on the mechanisms of DNA deformation, TATA element recognition, and preinitiation complex assembly. 1.9 A resolution refined structure of TBP recognizing the minor groove of TATAAAAG.,Kim JL, Burley SK Nat Struct Biol. 1994 Sep;1(9):638-53.
