Systematic analysis of low-affinity transcription factor binding site clusters in vitro and in vivo establishes their functional relevance

Sebastian Maerkl, Shiyu Cheng, Amir Shahein, Maria Lopez Malo, Evan James Olson, Ivan Istomin

Binding to binding site clusters has yet to be characterized in depth, and the functional relevance of low-affinity clusters remains uncertain. We characterized transcription factor binding to low-affinity clusters in vitro and found that transcription fac ...

Systematic analysis of biomolecular binding reactions using microfluidic systems

Amir Shahein

Transcription factor binding to a single binding site on DNA and its functional consequence in a promoter context are beginning to be relatively well understood. However, binding to clusters of sites has yet to be characterized in depth, and the functional ...

Computational identification and experimental characterization of preferred downstream positions in human core promoters

Philipp Bucher, René Dreos

Author summary Transcription of genes by the RNA polymerase II enzyme initiates at a genomic region termed the core promoter. The core promoter is a regulatory region that may contain diverse short DNA sequence motifs/elements that confer specific properti ...

The box C/D snoRNP assembly factor Bcd1 interacts with the histone chaperone Rtt106 and controls its transcription dependent activity

Benjamin Marcel Daniel Rothé

Biogenesis of eukaryotic box C/D small nucleolar ribonucleoproteins initiates co-transcriptionally and requires the action of the assembly machinery including the Hsp90/R2TP complex, the Rsa1p:Hit1p heterodimer and the Bcd1 protein. We present genetic inte ...

Transcription Factors and DNA Play Hide and Seek

David Michael Suter

Transcription factors (TFs) bind to specific DNA motifs to regulate the expression of target genes. To reach their binding sites, TFs diffuse in 3D and perform local motions such as 1D sliding, hopping, or intersegmental transfer. TF-DNA interactions depen ...

Opposing chromatin remodelers control transcription initiation frequency and start site selection

Philipp Bucher, René Dreos

Precise nucleosome organization at eukaryotic promoters is thought to be generated by multiple chromatin remodeler (CR) enzymes and to affect transcription initiation. Using an integrated analysis of chromatin remodeler binding and nucleosome occupancy fol ...

Single-molecule dynamics and genome-wide transcriptomics reveal that NF-kB (p65)-DNA binding times can be decoupled from transcriptional activation

Suliana Manley, Beat Fierz, David Michael Suter, Christian Sieben, Aleksandr Benke, Andrea Callegari

Transcription factors (TFs) regulate gene expression in both prokaryotes and eukaryotes by recognizing and binding to specific DNA promoter sequences. In higher eukaryotes, it remains unclear how the duration of TF binding to DNA relates to downstream tran ...

The yeast C/D box snoRNA U14 adopts a "weak" K-turn like conformation recognized by the Snu13 core protein in solution

Benjamin Marcel Daniel Rothé

Non-coding RNAs associate with proteins to form ribonucleoproteins (RNPs), such as ribosome, box C/D snoRNPs, H/ACA snoRNPs, ribonuclease P, telomerase and spliceosome to ensure cell viability. The assembly of these RNA-protein complexes relies on the abil ...

Functional Characterization of Nucleoid Associated Proteins Acting as Global Transcription Factors in Mycobacterium tuberculosis

Nina Theres Odermatt

The fatal lung disease tuberculosis is caused by the airborne Mycobacterium tuberculosis, a versatile pathogen adapted to rapidly changing environments. Instead of being eradicated by phagocytic cells of its human host, bacilli tune macrophages to support ...

The Genetics of Transcription Factor DNA Binding Variation

Bart Deplancke, Vincent Roland Julien Gardeux, Daniel Alpern

Most complex trait-associated variants are located in non-coding regulatory regions of the genome, where they have been shown to disrupt transcription factor (TF)-DNA binding motifs. Variable TF-DNA interactions are therefore increasingly considered as key ...

Influence of Rotational Nucleosome Positioning on Transcription Start Site Selection in Animal Promoters

Philipp Bucher, Giovanna Ambrosini, René Dreos

The recruitment of RNA-Pol-II to the transcription start site (TSS) is an important step in gene regulation in all organisms. Core promoter elements (CPE) are conserved sequence motifs that guide Pol-II to the TSS by interacting with specific transcription ...

Predicting transcription factor site occupancy using DNA sequence intrinsic and cell-type specific chromatin features

Philipp Bucher

Background: Understanding the mechanisms by which transcription factors (TF) are recruited to their physiological target sites is crucial for understanding gene regulation. DNA sequence intrinsic features such as predicted binding affinity are often not ve ...

Overexpression of the tcp Gene Cluster Using the T7 RNA Polymerase/Promoter System and Natural Transformation-Mediated Genetic Engineering of Vibrio cholerae

Melanie Blokesch

The human pathogen and aquatic bacterium Vibrio cholerae belongs to the group of naturally competent bacteria. This developmental program allows the bacterium to take up free DNA from its surrounding followed by a homologous recombination event, which allo ...

In-depth analysis of hyaline fibromatosis syndrome frameshift mutations at the same site reveal the necessity of personalized therapy

Matteo Dal Peraro, Françoise Gisou van der Goot Grunberg, Thomas Lemmin, Shixu Yan

Hyaline fibromatosis syndrome is an autosomal recessive disease caused by mutations in ANTXR2, a gene involved in extracellular matrix homeostasis. Sixty percent of patients carry frameshift mutations at a mutational hotspot in exon 13. We show in patient ...
