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.

Caution

The sequence shown here is derived from an EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is preliminary data.

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.
