Reanalysis of mtDNA mutations of human primordial germ cells (PGCs) reveals NUMT contamination and suggests that selection in PGCs may be positive

The resilience of the mitochondrial genome (mtDNA) to a high mutational pressure depends, in part, on negative purifying selection in the germline. A paradigm in the field has been that such selection, at least in part, takes place in primordial germ cells ...

Exploring the mechanisms governing nuclear cGAS localization and activity

Marilena Wischnewski

Recognition of pathogen-derived molecules through germline-encoded receptors is a fundamental principle of innate immunity. Pattern recognition receptors detect specific intracellular danger signals to trigger potent immune responses. The DNA sensor cyclic ...

cGAS regulation and activity during genotoxic stress

Sélène-Véronique Glück

The innate immune system has evolved to detect pathogens through germlineencoded pattern recognition receptors (PRRs). Nucleic acid sensors, a defined class of PRRs, bind to microbial and viral nucleic acids and trigger the production of type I interferons ...

Functional de novo Protein Design for Targeted Vaccines and Synthetic Biology Applications

Che Yang

Evolution has created, selected and evolved large repertoires of proteins that operate in various biological systems. Nowadays biotechnological needs are coming up orders of magnitude faster than proteins naturally evolve. The emergence of de novo protein ...

Chromatin is the template on which DNA-associated transactions take place in eukaryotic organisms. Nucleosomes consisting of the four histones H2A, H2B, H3 and H4 each organize ~150bp of DNA and constitute a first layer of chromatin. The three-dimensional ...

A two-state activation mechanism controls the histone methyltransferase Suv39h1

Beat Fierz

Specialized chromatin domains contribute to nuclear organization and regulation of gene expression. Gene-poor regions are di- and trimethylated at lysine 9 of histone H3 (H3K9me2 and H3K9me3) by the histone methyltransferase Suv39h1. This enzyme harnesses ...

Anillin is a scaffolding protein that organizes and stabilizes actomyosin contractile rings and was previously thought to function primarily in cytokinesis [1-10]. Using Xenopus laevis embryos as a model system to examine Anillin's role in the intact verte ...

Telomere length homeostasis

Joachim Lingner

The physical ends of chromosomes, known as telomeres, protect chromosome ends from nucleolytic degradation and DNA repair activities. Conventional DNA replication enzymes lack the ability to fully replicate telomere ends. In addition, nucleolytic activitie ...
