More than just a barrier: using physical models to couple membrane shape to cell function
The correct execution of many cellular processes, such as division and motility, requires the
cell to adopt a specific shape. Physically, these shapes are determined by the interplay of …

Clathrin coats partially preassemble and subsequently bend during endocytosis
Eukaryotic cells use clathrin-mediated endocytosis to take up a large range of extracellular
cargo. During endocytosis, a clathrin coat forms on the plasma membrane, but it remains …
