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 ...

Oscillating and stable genome topologies underlie hepatic physiological rhythms during the circadian cycle

Felix Naef, Jake Yeung, Jérôme Mermet

The circadian clock drives extensive temporal gene expression programs controlling daily changes in behavior and physiology. In mouse liver, transcription factors dynamics, chromatin modifications, and RNA Polymerase II (PolII) activity oscillate throughou ...

KAP1 targets actively transcribed genomic loci to exert pleomorphic effects on RNA polymerase II activity

Didier Trono, Evaristo Jose Planet Letschert, Marco Cassano, Annamaria Kauzlaric, Suk Min Jang

KAP1 (KRAB-associated protein 1) is best known as a co-repressor responsible for inducing heterochromatin formation, notably at transposable elements. However, it has also been observed to bind the transcription start site of actively expressed genes. To a ...

The ETFL formulation allows multi-omics integration in thermodynamics-compliant metabolism and expression models

Vassily Hatzimanikatis, Pierre Guy Rémy Salvy

Systems biology has long been interested in models capturing both metabolism and expression in a cell. We propose here an implementation of the metabolism and expression model formalism (ME-models), which we call ETFL, for Expression and Thermodynamics Flu ...

Human T-Cell Lymphotropic Virus Type 1 Transactivator Tax Exploits the XPB Subunit of TFIIH during Viral Transcription

Human T-cell lymphotropic virus type 1 (HTLV-1) Tax oncoprotein is required for viral gene expression. Tax transactivates the viral promoter by recruiting specific transcription factors but also by interfering with general transcription factors involved in ...

Computational study of transcription factor binding sites

Romain Fernand Pietro Groux

Any living organism contains a whole set of instructions encoded as genes on the DNA. This set of instructions contains all the necessary information that the organism will ever need, from its development to a mature individual to environment specific resp ...

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 ...

Modeling and analysis of parts and devices of genetic regulation

Yves Berset

DNA encrypts the composition of the cellular material that is synthesized through transcription and translation. Never-theless, gene regulation mechanisms determine the final amount of transcribed and translated material. Transcription factors (TF) are a c ...

Genomic targets and molecular partners of the chromatin regulator KAP1

Annamaria Kauzlaric

KAP1 is an enigmatic regulatory protein, first described some twenty years ago, shown to be involved in multiple and diverse cellular functions. Specifically, it mediates tasks critical to cell growth and differentiation, pluripotency, apoptosis, gene sile ...

Lysine acetylation stoichiometry and proteomics analyses reveal pathways regulated by sirtuin 1 in human cells

Diego Chiappe

Lysine acetylation is a widespread posttranslational modification affecting many biological pathways. Recent studies indicate that acetylated lysine residues mainly exhibit low acetylation occupancy, but challenges in sample preparation and analysis make i ...

Transcription-induced supercoiling explains formation of self-interacting chromatin domains in S-pombe

Yannis Burnier, Julien Dorier, Fabrizio Benedetti, Andrzej Stasiak

The question of how self-interacting chromatin domains in interphase chromosomes are structured and generated dominates current discussions on eukaryotic chromosomes. Numerical simulations using standard polymer models have been helpful in testing the vali ...

Transcriptional regulatory logic of the diurnal cycle in the mouse liver

Bart Deplancke, Matteo Dal Peraro, Felix Naef, Guillaume Rey, Frédéric Bruno Martin Gachon, Benjamin Dieter Weger, Sunil Kumar Raghav, Nouria Hernandez, Irina Krier, Alexandra Styliani Kalantzi, Jonathan Aryeh Sobel

Many organisms exhibit temporal rhythms in gene expression that propel diurnal cycles in physiology. In the liver of mammals, these rhythms are controlled by transcription-translation feedback loops of the core circadian clock and by feeding-fasting cycles ...
