Nanopore Detection of Single Molecule RNAP–DNA Transcription Complex

Aleksandra Radenovic, Erick Antonio Garcia Cordero, Camille Alice Raillon, Floriano Traversi

In the past decade, a number of single-molecule methods have been developed With the aim of investigating single protein and nucleic acid interactions. For the first time we use solid-state nanopore sensing to detect a single E. coli RNAP DNA transcription ...

The genome of Dehalobacter restrictus - high gene redundancy for a restricted metabolism

Christof Holliger, Julien Maillard, Aamani Rupakula Boyanapalli, Hauke Smidt

Organohalide respiration (OHR) is a bacterial anaerobic respiratory metabolism dedicated to use halogenated compounds as terminal electron acceptors. OHR bacteria are strictly anaerobic microorganisms which use reductive dehalogenases (RdhA) as key enzymes ...

Genomic context analysis reveals dense interaction network between vertebrate ultraconserved non-coding elements

Philipp Bucher, Slavica Dimitrieva Janeva

Motivation: Genomic context analysis, also known as phylogenetic profiling, is widely used to infer functional interactions between proteins but rarely applied to non-coding cis-regulatory DNA elements. We were wondering whether this approach could provide ...

The ATM substrate KAP1 controls DNA repair in heterochromatin: Regulation by HP1 proteins and Serine 473/824 phosphorylation

Didier Trono, Andrea Corsinotti

The repair of DNA damage in highly compact, transcriptionally silent heterochromatin requires that repair and chromatin packaging machineries be tightly coupled and regulated. KAP1 is a heterochromatin protein and co-repressor which binds to HP1 during gen ...

Development of a repressible mycobacterial promoter system based on two transcriptional repressors

Stewart Cole, Neeraj Dhar, Claudia Sala

Tightly regulated gene expression systems represent invaluable tools for studying gene function and for the validation of drug targets in bacteria. While several regulated bacterial promoters have been characterized, few of them have been successfully used ...

The telomere-binding protein Tbf1 demarcates snoRNA gene promoters in Saccharomyces cerevisiae

Felix Naef, Jacques Rougemont, Enrico Guarnera

Small nucleolar RNAs (snoRNAs) play a key role in ribosomal RNA biogenesis, yet factors controlling their expression are unknown. We found that the majority of Saccharomyces snoRNA promoters display an aRCCCTaa sequence motif at the upstream border of a TA ...

Analysis of the Pigment Cell Specific Gene MART-1/Melan-A/mlana

Iraz Toprak Aydin

Pigmentation is a complex process that provides many diverse benefits for the organism. Pigment production takes place in the pigment cell lineage in dedicated organelles called melanosomes. Several proteins are specifically recruited to melanosomes for th ...

Role of canonical Wnt signaling in mammary gland development

Renuga Devi Rajaram

The female reproductive hormones estrogens, progesterone, and prolactin control postnatal breast development and are important to breast carcinogenesis. In particular, exposure to progesterone is tightly linked to breast cancer risk. Using the mouse as a m ...

Genomic Context and KRAB/KAP1-mediated Transcriptional Repression

Sylvain Meylan

Chromatin structure and its impact on transcriptional activity represent one of the major revolutions in the biomedical field over the passed decade. The implications concern as much fundamental as clinically-oriented research; diseases and therapeutical s ...
