What is the normal function of the MFSD8 gene?
The MFSD8 gene provides instructions for making a protein whose function is unknown. The MFSD8 protein is found in cell compartments called lysosomes, which digest and recycle different types of molecules. The MFSD8 protein belongs to a large group of related proteins called the major facilitator superfamily of secondary active transporter proteins. Proteins in this family move certain molecules between structures in cells or in and out of cells. While it is likely that the MFSD8 protein transports molecules, the specific molecules it moves are unknown. The MFSD8 protein probably transports substances across the membranes of lysosomes.
