Question

which proteins play a central role in the fusion of a vesicle with a target membrane? choose one: clathrin tethering proteins adaptin rab proteins snares

Explanation:

SNAREs (Soluble N - ethylmaleimide - sensitive factor attachment protein receptors) are key proteins for vesicle - target membrane fusion. They form a complex that brings the vesicle and target membranes into close proximity, facilitating fusion. Clathrin is involved in vesicle formation, tethering proteins help in initial docking, adaptin is related to clathrin - coated vesicle assembly, and Rab proteins regulate vesicle trafficking and docking but SNAREs are central to the fusion step.

Answer:

SNAREs
