Structural basis of ER-associated protein degradation mediated by the Hrd1 ubiquitin ligase complex

X Wu, M Siggel, S Ovchinnikov, W Mi, V Svetlov… - Science, 2020 - science.org
INTRODUCTION Protein homeostasis in the endoplasmic reticulum (ER) is maintained by a
quality control system. When a newly synthesized ER protein misfolds, it is ultimately …

AI-based structure prediction empowers integrative structural analysis of human nuclear pores

S Mosalaganti, A Obarska-Kosinska, M Siggel… - Science, 2022 - science.org
INTRODUCTION The eukaryotic nucleus protects the genome and is enclosed by the two
membranes of the nuclear envelope. Nuclear pore complexes (NPCs) perforate the nuclear …

[HTML][HTML] Visualizing the disordered nuclear transport machinery in situ

…, CD Reinkemeier, A Obarska-Kosinska, M Siggel… - Nature, 2023 - nature.com
The approximately 120 MDa mammalian nuclear pore complex (NPC) acts as a gatekeeper
for the transport between the nucleus and cytosol 1 . The central channel of the NPC is filled …

FAM134B-RHD protein clustering drives spontaneous budding of asymmetric membranes

M Siggel, RM Bhaskara, MK Moesser… - The journal of …, 2021 - ACS Publications
Living cells constantly remodel the shape of their lipid membranes. In the endoplasmic
reticulum (ER), the reticulon homology domain (RHD) of the reticulophagy regulator 1 (RETR1/…

Dynamic cluster formation determines viscosity and diffusion in dense protein solutions

S von Bülow, M Siggel, M Linke… - Proceedings of the …, 2019 - National Acad Sciences
We develop a detailed description of protein translational and rotational diffusion in concentrated
solution on the basis of all-atom molecular dynamics simulations in explicit solvent. Our …

Phospholipid scramblases remodel the shape of asymmetric membranes

M Siggel, RM Bhaskara, G Hummer - The Journal of Physical …, 2019 - ACS Publications
The cell membrane and many organellar membranes are asymmetric and highly curved. In
experiments, it is challenging to reconstitute and characterize membranes that differ in the …

[PDF][PDF] PyContact: rapid, customizable, and visual analysis of noncovalent interactions in MD simulations

M Scheurer, P Rodenkirch, M Siggel, RC Bernardi… - Biophysical journal, 2018 - cell.com
Molecular dynamics (MD) simulations have become ubiquitous in all areas of life sciences.
The size and model complexity of MD simulations are rapidly growing along with increasing …

[HTML][HTML] Variable microtubule architecture in the malaria parasite

JL Ferreira, V Pražák, D Vasishtan, M Siggel… - Nature …, 2023 - nature.com
Microtubules are a ubiquitous eukaryotic cytoskeletal element typically consisting of 13
protofilaments arranged in a hollow cylinder. This arrangement is considered the canonical form …

Membrane fusion and drug delivery with carbon nanotube porins

NT Ho, M Siggel, KV Camacho… - Proceedings of the …, 2021 - National Acad Sciences
Drug delivery mitigates toxic side effects and poor pharmacokinetics of life-saving therapeutics
and enhances treatment efficacy. However, direct cytoplasmic delivery of drugs and …

Artificial intelligence reveals nuclear pore complexity

S Mosalaganti, A Obarska-Kosinska, M Siggel… - BioRxiv, 2021 - biorxiv.org
Nuclear pore complexes (NPCs) mediate nucleocytoplasmic transport. Their intricate 120 MDa
architecture remains incompletely understood. Here, we report a near-complete structural …
