Predicted to enable transmembrane transporter activity. Acts upstream of or within several processes, including TORC1 signaling; autophagosome maturation; and regulation of cellular catabolic process. Located in lysosome and membrane. Is expressed in several structures, including brain; cardiovascular system; genitourinary system; gut; and respiratory system. Used to study neuronal ceroid lipofuscinosis 7. Human ortholog(s) of this gene implicated in neuronal ceroid lipofuscinosis 7. Orthologous to human MFSD8 (major facilitator superfamily domain containing 8).
