Membrane Trafficking: Decoding Vesicle Identity With Contrasting Chemistries

Curr Biol. 2011 Oct 11;21(19):R811-3. doi: 10.1016/j.cub.2011.08.045.

Abstract

Proteins involved in membrane traffic must distinguish between different classes of vesicles. New work now shows that α-synuclein and ALPS motifs represent two extreme types of amphipathic helix that are tuned to detect both the curvature of transport vesicles as well as their bulk lipid content.
