The image shows how SNARE proteins (in salmon color) initiate the fusion of two membranes by facilitating encounters of their water-repelling tails (yellow and green) at the water-filled interface ...

Dynamin is a protein that plays a central role in endocytosis—the process where cells internalize substances by wrapping them in cell membrane vesicles. For a vesicle to detach, the neck of the ...

Dynamin assembles into a ring around the neck of a forming vesicle and utilizes GTP hydrolysis energy to constrict and sever the membrane. The simulation reveals that the dynamin ring expands (loosens ...
