These GTPases, which associate with and dissociate from donor membranes in a guanosine triphosphate-dependent manner, can also actively remodelmembranes.

Here, we detail the assays we used to explore the cooperative action of Arf1 and exomer to bind and remodelmembranes.

The small GTPase Arf1 and related proteins have the ability to remodelmembranes by insertion of an amphipathic helix into the membrane.
