Bidirectional binding of the TATA box binding protein to the TATA box.
By selective attachment of a DNA cleavage agent to specific residues in the yeast TATA box binding protein (yTBP), we demonstrate that, in solution, yTBP binds to the TATA boxes of both the adenovirus major late promoter and the yeast CYC1 promoter with only a modest preference in orientation and binds well to several overlapping binding sites. The general factors TFIIA and TFIIB each increase ...
متن کاملSelective binding of the TATA box-binding protein to the TATA box-containing promoter: analysis of structural and energetic factors.
We report the results of an energy-based exploration of the components of selective recognition of the TATA box-binding protein (TBP) to a TATA box sequence that includes 1) the interaction between the hydrophobic Leu, Pro, and Phe residues of TBP with the TA, AT, AA, TT, and CG steps, by ab initio quantum mechanical calculations; and 2) the free energy penalty, calculated from molecular dynami...
متن کاملThe small nuclear RNA-activating protein 190 Myb DNA binding domain stimulates TATA box-binding protein-TATA box recognition.
Human U6 small nuclear RNA (snRNA) gene transcription by RNA polymerase III requires cooperative promoter binding involving the snRNA-activating protein complex (SNAP(c)) and the TATA-box binding protein (TBP). To investigate the role of SNAP(c) for TBP function at U6 promoters, TBP recruitment assays were performed using full-length TBP and a mini-SNAP(c) containing SNAP43, SNAP50, and a trunc...
متن کاملCrystal structure of a human TATA box-binding protein/TATA element complex.
The TATA box-binding protein (TBP) is required by all three eukaryotic RNA polymerases for correct initiation of transcription of ribosomal, messenger, small nuclear, and transfer RNAs. The cocrystal structure of the C-terminal/core region of human TBP complexed with the TATA element of the adenovirus major late promoter has been determined at 1.9 angstroms resolution. Structural and functional...
متن کاملTATA element recognition by the TATA box-binding protein has been conserved throughout evolution.
Cocrystal structures of wild-type TATA box-binding protein (TBP) recognizing 10 naturally occurring TATA elements have been determined at 2.3-1.8 A resolution, and compared with our 1.9 A resolution structure of TBP bound to the Adenovirus major late promoter (AdMLP) TATA box (5'-TATAAAAG-3'). Minor-groove recognition by the saddle-shaped protein induces the same conformational change in each o...
