Function
function
Lysosomal dipeptide uniporter that selectively exports lysine, arginine or histidine-containing dipeptides with a net positive charge from the lysosome lumen into the cytosol. Could play a role in a specific type of protein O-glycosylation indirectly regulating macrophages migration and tissue invasion. Also essential for liver homeostasis.

Interaction
Subunit
Homodimer. Interacts with lysosomal protein GLMP (via lumenal domain); the interaction starts while both proteins are still in the endoplasmic reticulum and is required for stabilization of MFSD1 in lysosomes but has no direct effect on its targeting to lysosomes or transporter activity.
