Tube-forming lipid transport protein which probably mediates the transfer of lipids between membranes at organelle contact sites (PubMed:35499567). May be involved in the retrograde traffic of vesicle clusters in the endocytic pathway to the Golgi complex (PubMed:35499567). . This is the function of Ensembl gene identifier ENSG00000065060 (BLTP3A, bridge-like lipid transfer protein family member 3A).
