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 ...

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, Béatrice Kunz, Luciano Andres Abriata, Sylvia Ho, Catherine Maclachlan, Patrick Alain Sandoz, Gard Spreemann, Robin Alexander Denhardt-Eriksson

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 ...

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 ...

Torsin ATPases influence chromatin interaction of the Torsin regulator LAP1

Rudolf Hovius, Beat Fierz

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 ...

Spatial control of nucleoporin condensation by fragile X-related proteins

Alessandro Berto

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 ...

BAF 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 ...

Chromatin 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 ...

Biophysics of Chromatin Dynamics

Beat Fierz

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 ...

Dynamic protein-chromatin interactions in heterochromatin and during the DNA damage response on the single molecule level

Andreas Linus Bachmann

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 ...

Computer simulations reveal mechanisms that organize nuclear dynein forces to separate centrosomes

Pierre Gönczy, Alessandro De Simone

Centrosome separation along the surface of the nucleus at the onset of mitosis is critical for bipolar spindle assembly. Dynein anchored on the nuclear envelope is known to be important for centrosome separation, but it is unclear how nuclear dynein forces ...

Dynein Transmits Polarized Actomyosin Cortical Flows to Promote Centrosome Separation

Pierre Gönczy, Alessandro De Simone

The two centrosomes present at the onset of mitosis must separate in a timely and accurate fashion to ensure proper bipolar spindle assembly. The minus-end-directed motor dynein plays a pivotal role in centrosome separation, but the underlying mechanisms r ...

Mechanisms of centrosome separation in C. elegans

Alessandro De Simone

Centrosomes are the major microtubule organizing centers of animal cells. The two centrosomes present at the onset of mitosis must separate in a timely fashion along the nuclear envelope to ensure proper bipolar spindle assembly and thus genome stability. ...

Conditional expression of Parkinson's disease-related R1441C LRRK2 in midbrain dopaminergic neurons of mice causes nuclear abnormalities without neurodegeneration

Graham Knott, Liliane Glauser, Elpida Tsika, Darren Moore, Shi-Yan Caroline Foo, Meghna Kannan

Mutations in the leucine-rich repeat kinase 2 (LRRK2) gene cause late-onset, autosomal dominant Parkinson's disease (PD). The clinical and neurochemical features of LRRK2-linked PD are similar to idiopathic disease although neuropathology is somewhat heter ...

Selective transport control on molecular velcro made from intrinsically disordered proteins

Sylvia Jeney

The selectivity and speed of many biological transport processes(1) transpire from a 'reduction of dimensionality'(2) that confines diffusion to one or two dimensions instead of three(3). This behaviour remains highly sought after on polymeric surfaces(4) ...

Automatic Tracking of Individual Fluorescence Particles: Application to the Study of Chromosome Dynamics

Michaël Unser, Daniel Sage

We present a new, robust, computational procedure for tracking fluorescent markers in time-lapse microscopy. The algorithm is optimized for finding the time-trajectory of single particles in very noisy dynamic (two- or three-dimensional) image sequences. I ...
