| Short Name | VPS13_DH-like |
| description | This entry represents a domain reminiscent of a DH domain (DH-Like domain) found adjacent the C-terminal PH-like domain of VPS13 proteins [, , , ]. DHL-PH domains has been identified as the mitochondria-binding region of VPS13A and the lipid droplet-binding region of both proteins. These two domains contain a region of high similarity to ATG2, which also binds lipid droplets [, ].VPS13 proteins have been implicated in processes including vesicle fusion, autophagy, and actin regulation. They bind phospholipids and act as channels that mediate the transfer of lipids between membranes at organelle contact sites [, , ]. 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. Most evidence showed that mammalian VPS13A, VPS13C and VPS13D localize 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 localize to endosome-endosome contacts [, , ]. Mutations in human VPS13 proteins (VPS13A-D) cause different diseases such as Chorea-acanthocytosis, Cohen syndrome, Parkinson's disease, and spastic ataxia, respectively which suggests they have different functions [, ]. |
