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 [3,4,5]. These proteins may bind and transfer tens of glycerolipids at once. Mutations in human VPS13 proteins cause different diseases such as Chorea-acanthocytosis, Cohen syndrome or Parkinson's disease [6,7]. This is the C-terminal domain of VPS13, a reminiscent of a DH domain (DH-Like domain) which has been identified as the mitochondria-binding region of VPS13A together with the PH-like (Pfam:PF09333).
