The following text describes a protein:
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 Localization:
Mitochondrion outer membrane; Peripheral membrane protein. Endoplasmic reticulum membrane; Peripheral membrane protein. Endosome membrane; Peripheral membrane protein. Lysosome membrane; Peripheral membrane protein. Lipid droplet. Golgi apparatus. Cytoplasmic vesicle, secretory vesicle, neuronal dense core vesicle. Note=Localizes at mitochondria-endosomes and mitochondria-endoplasmic reticulum contact sites.
Domain:
The C-terminal part (3058-3174) is involved in phospholipid binding, including phosphatidylinositol 4,5-bisphosphate; The FFAT motif is required for interaction with VAPA and VAPB and its localization to the endoplasmic reticulum.
