Structures and implications of TBP–nucleosome complexes [PDF]

open access: yesProceedings of the National Academy of Sciences, 2021
Significance The TATA box-binding protein (TBP) is highly conserved throughout eukaryotes and plays a central role in the assembly of the transcription preinitiation complex (PIC) at the promoter of genes. We show here that TBP can interact with nucleosomes containing the Widom-601 sequence at two different positions. One position comprises a

Human_SNP_TATAdb: a database of SNPs that statistically significantly change the affinity of the TATA-binding protein to human gene promoters: genome-wide analysis and use cases

open access: yesВавиловский журнал генетики и селекции, 2023
It was previously shown that the expression levels of human genes positively correlate with TBP affinity for the promoters of these genes. In turn, single nucleotide polymorphisms (SNPs) in human gene promoters can affect TBP affinity for DNA and, as a ...

Solvent Extraction of Didymium by TBP, Aliquat 336 and HDEHP in The Presence of Ca(NO3)2

open access: yesApplied Sciences, 2020
Three commercially available extractants (tri-butyl-phosphate (TBP), di-(2-ethylhexyl)phosphoric acid (HDEHP) and Aliquat 336 (a mixture of quaternary ammonium bases)) were tested for separation of Pr(III) and Nd(III) in both static and dynamic modes. In

Effects of the Structure of Benzenesulfonate-Based Draw Solutes on the Forward Osmosis Process

open access: yesMembranes, 2022
A series of phosphonium-based ionic liquids (ILs) based on benzenesulfonate derivatives (tetrabutylphosphonium benzenesulfonate ([TBP][BS]), tetrabutylphosphonium 4-methylbenzenesulfonate ([TBP][MBS]), tetrabutylphosphonium 2,4-dimethylbenzenesulfonate ([

TBP Dynamics in Living Human Cells: Constitutive Association of TBP with Mitotic Chromosomes [PDF]

open access: yesMolecular Biology of the Cell, 2002
The recruitment of TATA binding protein (TBP) to gene promoters is a critical rate-limiting step in transcriptional regulation for all three eukaryotic RNA polymerases. However, little is known regarding the dynamics of TBP in live mammalian cells. In this report, we examined the distribution and dynamic behavior of green fluorescence protein (GFP ...

RNA Polymerase II transcription independent of TBP in murine embryonic stem cells

open access: yeseLife, 2023
Transcription by RNA Polymerase II (Pol II) is initiated by the hierarchical assembly of the pre-initiation complex onto promoter DNA. Decades of research have shown that the TATA-box binding protein (TBP) is essential for Pol II loading and initiation ...

The TATA‐Box‐Binding Protein (TBP) of Halobacterium Salinarum [PDF]

open access: yesEuropean Journal of Biochemistry, 1997
The TATA‐box binding protein (TBP) is a basal transcription factor involved in transcription initiation in Eucarya and Archaea. Using a tbp‐specific probe, a 4.5‐kbp genomic fragment from Halobacterium salinarum was cloned and sequenced. It contained the tbp gene and the 5’‐ends of two additional open reading frames, but surprisingly, 70% of the cloned
