Vesicle transport

Transfer of cargo in membrane-bounded vesicles. Budding selects material and produces a carrier, while targeting and vesicle fusion deliver it to another compartment, allowing transport without exposing the cargo directly to the surrounding cytoplasm.

Merger of a vesicle membrane with a target membrane. The process connects the two enclosed aqueous spaces or releases cargo outside the cell, while also transferring membrane components to the target surface.

A membrane-bounded carrier that delivers cargo toward the cell surface for release. Fusion with the cell membrane exposes the vesicle’s interior to the extracellular space, connecting intracellular packaging with secretion.
