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 کاملDynamics of TBP binding to the TATA box
Gene expression is highly controlled and regulated in living cells. One of the first steps in gene transcription is recognition of the promoter site by the TATA box Binding Protein (TBP). TBP recruits other transcriptions factors and eventually the RNA polymerase II to transcribe the DNA in mRNA. We developed a single pair Förster Resonance Energy Transfer (spFRET) assay to investigate the mech...
متن کاملGal4-VP16 and Gal4-AH increase the orientational and axial specificity of TATA box recognition by TATA box binding protein.
Previous work has shown that binding of the TATA box binding protein (TBP) to the TATA box is a rate-limiting step during pre-initiation complex (PIC) formation. Although the transcription of eukaryotic genes normally proceeds in one direction, studies in solution have shown that TBP lacks the information necessary to orient itself on the TATA box. Instead, yeast TBP binds TATA-containing promo...
