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.

Solute carrier family 46 member 1, also called Proton-coupled folate transporter, of the Major Facilitator Superfamily of transporters; Solute carrier family 46 member 1 (SLC46A1) is also called proton-coupled folate transporter (PCFT), G21, or heme carrier protein 1 (HCP1). It functions in two ways: as an intestinal proton-coupled high-affinity folate transporter that facilitates the absorption of folates across the brush-border membrane of the small intestine; and as an intestinal heme transporter which mediates heme uptake from the gut lumen into duodenal epithelial cells. It displays a higher affinity for folate than heme. It is also expressed in the choroid plexus and is required for transport of folates into the cerebrospinal fluid. Loss of function mutations in the SLC46A1 gene results in the autosomal recessive disorder "hereditary folate malabsorption" (HFM), characterized by severe systemic and cerebral folate deficiency. SLC46A1 belongs to the Eukaryotic Solute carrier 46 (SLC46)/Bacterial Tetracycline resistance (TetA) -like (SLC46/TetA-like) family of the Major Facilitator Superfamily (MFS) of transporters. MFS proteins are thought to function through a single substrate binding site, alternating-access mechanism involving a rocker-switch type of movement.

Major facilitator superfamily domain-containing protein 10; Major facilitator superfamily domain-containing protein 10 (MFSD10) is also called tetracycline transporter-like protein (TETRAN). It is expressed in various human tissues, including the kidney. In cultured cells, its overexpression facilitated the uptake of organic anions such as some non-steroidal anti-inflammatory drugs (NSAIDs). MFSD10/TETRAN overexpression cause resistance to some NSAIDs, suggesting that it may be an organic anion transporter that serves as an efflux pump for some NSAIDs and various other organic anions at the final excretion step. MFSD10 belongs to the Eukaryotic Solute carrier 46 (SLC46)/Bacterial Tetracycline resistance (TetA) -like (SLC46/TetA-like) family of the Major Facilitator Superfamily (MFS) of transporters.
