Protein: Intermembrane lipid transfer protein VPS13A (Chorea-acanthocytosis protein) (Chorein) (Vacuolar protein sorting-associated protein 13A) (Q96RL7)
Organism: Homo sapiens (Human)
Function: Mediates the transfer of lipids between membranes at organelle contact sites (By similarity). Binds phospholipids. Required for the formation or stabilization of ER-mitochondria contact sites which enable transfer of lipids between the ER and mitochondria. Negatively regulates lipid droplet size and motility. Required for efficient lysosomal protein degradation.
Subcellular location: Mitochondrion outer membrane {ECO:0000269|PubMed:30093493, ECO:0000269|PubMed:30709847, ECO:0000269|PubMed:30741634}; Peripheral membrane protein {ECO:0000269|PubMed:30741634}.
