The nucleus is surrounded by the nuclear envelope (NE), which is formed by two juxtaposed membranes, termed the inner and outer nuclear membranes. A protein meshwork of intermediate filament proteins ...

SNARE proteins are essential for intracellular membrane fusion of eukaryotes. Their assembly into stable four-helix bundles bridges membranes and may provide the energy for initiating membrane fusion.

Stress granules are droplet-like protein hubs that temporarily shield fragile RNA from cellular stresses such as toxins. VCP is a protein essential for breaking up stress granules and has been linked ...

Exact part location and minimal clearances seem like the Holy Grail of precision mechanical systems. But insisting on the slimmest tolerances can make assembly and disassembly difficult. Assembly ...
