Major Facilitator Superfamily; The Major Facilitator Superfamily (MFS) is a large and diverse group of secondary transporters that includes uniporters, symporters, and antiporters. MFS proteins facilitate the transport across cytoplasmic or internal membranes of a variety of substrates including ions, sugar phosphates, drugs, neurotransmitters, nucleosides, amino acids, and peptides. They do so using the electrochemical potential of the transported substrates. Uniporters transport a single substrate, while symporters and antiporters transport two substrates in the same or in opposite directions, respectively, across membranes. MFS proteins are typically 400 to 600 amino acids in length, and the majority contain 12 transmembrane alpha helices (TMs) connected by hydrophilic loops. The N- and C-terminal halves of these proteins display weak similarity and may be the result of a gene duplication/fusion event. Based on kinetic studies and the structures of a few bacterial superfamily members, GlpT (glycerol-3-phosphate transporter), LacY (lactose permease), and EmrD (multidrug transporter), MFS proteins are thought to function through a single substrate binding site, alternating-access mechanism involving a rocker-switch type of movement. Bacterial members function primarily for nutrient uptake, and as drug-efflux pumps to confer antibiotic resistance. Some MFS proteins have medical significance in humans such as the glucose transporter Glut4, which is impaired in type II diabetes, and glucose-6-phosphate transporter (G6PT), which causes glycogen storage disease when mutated.

Bacterial fucose permease, eukaryotic Major facilitator superfamily domain-containing protein 4, and similar proteins; This family is composed of bacterial L-fucose permease (FucP), eukaryotic Major facilitator superfamily domain-containing protein 4 (MFSD4) proteins, and similar proteins. L-fucose permease facilitates the uptake of L-fucose across the boundary membrane with the concomitant transport of protons into the cell; it can also transport L-galactose and D-arabinose. The MFSD4 subfamily consists of two vertebrate members: MFSD4A and MFSD4B. The function of MFSD4A is unknown. MFSD4B is more commonly know as Sodium-dependent glucose transporter 1 (NaGLT1), a primary fructose transporter in rat renal brush-border membranes that also facilitates sodium-independent urea uptake. The FucP/MFSD4 family belongs to the Major Facilitator Superfamily (MFS) of membrane transport proteins, which are thought to function through a single substrate binding site, alternating-access mechanism involving a rocker-switch type of movement.
