Major facilitator superfamily domain-containing protein 9 is a protein that in humans is encoded by the MFSD9 gene. It is a potential solute carrier, and called atypical solute carrier[5] since it is not named according to the SLC nomenclature.[6] It is expressed both in central and peripheral organs.[7]
