Dynamics 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 PORTFOLIO2023Simultaneous membrane and RNA binding by Tick-Borne Encephalitis Virus capsid protein
Tick-borne encephalitis virus is an enveloped, pathogenic, RNA virus in the family Flaviviridae, genus Flavivirus. Viral particles are formed when the nucleocapsid, consisting of an RNA genome and multiple copies of the capsid protein, buds through the end ...
PUBLIC LIBRARY SCIENCE2023Development 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 ...
EPFL2022Pde-Constrained Optimization For Nuclear Mechanics
We propose an image based PDE-constrained optimisation framework to compute the dynamical quantities of a cell nucleus undergoing deformation. It allows retrieving the displacement, strain and stress at each pixel of the nuclear domain, as well as the trac ...
IEEE2022Torsin 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 ...
2020Organelle-specific targeting of polymersomes into the cell nucleus
Organelle-specific nanocarriers (NCs) are highly sought after for delivering therapeutic agents into the cell nucleus. This necessitates nucleocytoplasmic transport (NCT) to bypass nuclear pore complexes (NPCs). However, little is known as to how comparabl ...
2020Mechanosensitive Fluorescent Probes to Image Membrane Tension in Mitochondria, Endoplasmic Reticulum, and Lysosomes
Suliana Manley, Stefan Matile, Dora Mahecic
Measuring forces inside cells is particularly challenging. With the development of quantitative microscopy, fluorophores which allow the measurement of forces became highly desirable. We have previously introduced a mechanosensitive flipper probe, which re ...
