They bind phospholipids and act as channels that mediate the transfer of lipids between membranes at organelle contact sites [2-5]. It has been proposed that members of this entry have the capacity to bind and likely transfer tens of glycerolipids at once. Yeast VPS13 acts at multiple cellular sites, namely the interface between mitochondria and the vacuole, on endosomes, on the nuclear-vacuole junction and the vacuole, depending on the carbon source and metabolic state. VPS13A, VPS13C and VPS13D from mammals localise at contacts at contacts between the ER and other organelles, i.e. VPS13A and VPS13D bridge the ER to mitochondria, VPS13C bridges the ER to late endosomes and lysosomes and VPS13B may localise to endosome-endosome contacts [3-5]. Mutations in human VPS13 proteins cause different diseases such as Chorea-acanthocytosis, Cohen syndrome, Parkinson's disease, and spastic ataxia [1]. ATG2 is involved in autophagosome assembly playing a key role in nonvesicular lipid transfer [6]. This is the N-terminal chorein domain of VPS13 and ATG2 proteins which is highly conserved [2-5]. It has a scoop shape whose concave surface is lined by hydrophobic residues which bind glycerophospholipids [6,7].
