Abstract

VPS13 proteins, whose dysfunction in humans underlies neurological disorders including Huntington‐like and early onset Parkinson’s diseases, are lipid transport protein active at membrane contact sites. VPS13 and proteins related by the presence of a chorein_N sequence, such as the autophagy protein ATG2, constitute a novel class of lipid transporters that solubilize tens of lipids within a wide hydrophobic channel. An intriguing possibility is that these proteins are bridges across which glycerolipids traverse the cytosol between membranes.
