Membrane 'neighborhood' helps transporter protein regulate cell signaling

When a cell receives a message from outside, it generates a molecule called cyclic AMP (cAMP) to relay this message. To ...

Simulations reveal protein 'dynamin' constricts cell membranes by loosening its grip

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 ...
