Control of nuclear envelope dynamics during acute ER stress by LINC complexes disassembly and selective, asymmetric autophagy of the outer nuclear membrane
The endoplasmic reticulum (ER) extends to the outer (ONM) and the inner (INM) nuclear membrane forming the nuclear envelope (NE) that delimits the nucleoplasm containing the cell genome. Unfolded protein responses (UPRs) and reticulophagy responses increas ...
Philadelphia2024Dynamics of CLIMP-63 S-acylation control ER morphology
Vassily Hatzimanikatis, Françoise Gisou van der Goot Grunberg, Graham Knott, Kathryn Hess Bellwald, Laurence Gouzi Abrami, Luciano Andres Abriata, Béatrice Kunz, Sylvia Ho, Patrick Alain Sandoz, Catherine Maclachlan, Robin Alexander Denhardt-Eriksson, Gard Spreemann
A key player in the formation of endoplasmic reticulum sheets is CLIMP-63, but mechanistic details remained elusive. Here authors combined cellular experiments and mathematical modelling to show that S-acylation of CLIMP-63 regulates its function by mediat ...
NATURE PORTFOLIO2023Development of multiplexed single-molecule imaging techniques to study chromatin invasion dynamics of chromatin effector proteins
DNA-binding proteins physically interact with the DNA and directly affect genomic functions. The eukaryotic genome is compacted into chromatin, limiting the DNA access to nuclear factors. In this Ph.D. thesis, I explored the dynamic mechanisms, that allow ...
EPFL2023Exploring the mechanisms governing nuclear cGAS localization and activity
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 ...
EPFL2022Torsin ATPases influence chromatin interaction of the Torsin regulator LAP1
The inner nuclear membrane is functionalized by diverse transmembrane proteins that associate with nuclear lamins and/or chromatin. When cells enter mitosis, membrane-chromatin contacts must be broken to allow for proper chromosome segregation; yet how thi ...
ELIFE SCIENCES PUBLICATIONS LTD2020Spatial control of nucleoporin condensation by fragile X-related proteins
Nucleoporins (Nups) build highly organized nuclear pore complexes (NPCs) at the nuclear envelope (NE). Several Nups assemble into a sieve-like hydrogel within the central channel of the NPCs. In the cytoplasm, the soluble Nups exist, but how their assembly ...
WILEY2020BAF restricts cGAS on nuclear DNA to prevent innate immune activation
Mahmut Selman Sakar, Beat Fierz, Andrea Ablasser, Baptiste Claude André Guey, Alexiane Clara Decout, Murat Kaynak, Kristina Makasheva, Marilena Wischnewski
The appearance of DNA in the cytosol is perceived as a danger signal that stimulates potent immune responses through cyclic guanosine monophosphate–adenosine monophosphate synthase (cGAS). How cells regulate the activity of cGAS toward self-DNA and guard a ...
2020Chromatin three-dimensional interactions mediate genetic effects on gene expression
David Hacker, Giovanna Ambrosini, Philipp Bucher, Sanjeev Kumar
Studying the genetic basis of gene expression and chromatin organization is key to characterizing the effect of genetic variability on the function and structure of the human genome. Here we unravel how genetic variation perturbs gene regulation using a da ...
2019Biophysics of Chromatin Dynamics
Nucleosomes and chromatin control eukaryotic genome accessibility and thereby regulate DNA processes, including transcription, replication, and repair. Conformational dynamics within the nucleosome and chromatin structure play a key role in this regulatory ...
ANNUAL REVIEWS2019Dynamic protein-chromatin interactions in heterochromatin and during the DNA damage response on the single molecule level
Dynamic regulation of chromatin, a structure consisting of DNA and histone proteins, is mediated through histone post-translational modifications (PTMs) and effector proteins. HP1a and PRC2 are recruited to repressive PTMs (H3K9me3, H3K27me3) and enable he ...
