Trypanosoma brucei UMSBP2 is a single-stranded telomeric DNA binding protein essential for chromosome end protection

Galina Glousker

Universal minicircle sequence binding proteins (UMSBPs) are CCHC-type zinc-finger proteins that bind a single-stranded G-rich sequence, UMS, conserved at the replication origins of the mitochondrial (kinetoplast) DNA of trypanosomatids. Here, we report tha ...

KRAB'n'KAP, DNA methylation and epigenetic memory

Andrea Coluccio

The KZFP/KAP1 (Krüppel associated box zinc finger proteins/KRAB-associated protein 1) complex is a transcriptional repressor that triggers the deposition of heterochromatin (H3K9me3) and DNA methylation. The main targets of the KZFP/KAP1 complex are transp ...

KRAB zinc-finger proteins contribute to the evolution of gene regulatory networks

Didier Trono, Michaël Imbeault, Pierre-Yves Joseph Laurent Helleboid

The human genome encodes some 350 Kruppel-associated box (KRAB) domain-containing zinc-finger proteins (KZFPs), the products of a rapidly evolving gene family that has been traced back to early tetrapods(1,2). The function of most KZFPs is unknown, but a f ...

Whole genome grey and white matter DNA methylation profiles in dorsolateral prefrontal cortex

Johannes Gräff, Jose Vicente Sanchez Mut

The brain's neocortex is anatomically organized into grey and white matter, which are mainly composed by neuronal and glial cells, respectively. The neocortex can be further divided in different Brodmann areas according to their cytoarchitectural organizat ...

Spatial organization of DNA sequences directs the assembly of bacterial chromatin by a nucleoid-associated protein

Giovanni Dietler, Aleksandre Japaridze, Sylvain Renevey

Structural differentiation of bacterial chromatin depends on cooperative binding of abundant nucleoid-associated proteins at numerous genomic DNA sites and stabilization of distinct long-range nucleoprotein structures. Histone-like nucleoid-structuring pro ...

Quantification of Cooperativity in Heterodimer-DNA Binding Improves the Accuracy of Binding Specificity Models

Vassily Hatzimanikatis, Bart Deplancke, Alina Isakova, Yves Berset

Many transcription factors (TFs) have the ability to cooperate on DNA elements as heterodimers. Despite the significance of TF heterodimerization for gene regulation, a quantitative understanding of cooperativity between various TF dimer partners and its i ...

Screening of structurally diverse bicyclic peptide libraries by phage display

Davide Bertoldo

Bicyclic peptides are an attractive molecule format for the development of therapeutics and research tools. Our laboratory is specialized on the development of bicyclic peptide ligands by phage display. In brief, libraries of randompeptides each containing ...

Unraveling the KRAB/KAP1 control of transposable elements in pluripotent and somatic cells

Gabriela Ecco

Transposable elements (TEs) are DNA sequences able to change position in the genome, and represent more than 40% of mammalian genetic material. TEs can have positive or detrimental effects on the host, being both important motors of evolution and genomic t ...

Epigenetic Alterations in Alzheimer's Disease

Johannes Gräff, Jose Vicente Sanchez Mut

Alzheimer's disease (AD) is the major cause of dementia in Western societies. It progresses asymptomatically during decades before being belatedly diagnosed when therapeutic strategies have become unviable. Although several genetic alterations have been as ...

Methyl Supplementation Attenuates Cocaine-Seeking Behaviors and Cocaine-Induced c-Fos Activation in a DNA Methylation-Dependent Manner

Fiona Hollis

Epigenetic mechanisms, such as histone modifications, regulate responsiveness to drugs of abuse, such as cocaine, but relatively little is known about the regulation of addictive-like behaviors by DNA methylation. To investigate the influence of DNA methyl ...
