Unlike the other SLC37 members, lacks glucose-6-phosphate antiporter activity (PubMed:21949678). In osteoclasts, forms a transporter complex with ATRAID for nitrogen-containing-bisphophonates (N-BPs) required for releasing N-BP molecules that have trafficked to lysosomes through fluid-phase endocytosis into the cytosol (PubMed:29745899). {ECO:0000269|PubMed:21949678, ECO:0000269|PubMed:29745899}. This is the function of ENSG00000157800 (SLC37A3, solute carrier family 37 member 3).
