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 22, member 17 of the Major Facilitator Superfamily; Solute carrier family 22, member 17 (SLC22A17) is also called 24p3 receptor (24p3R), lipocalin-2 receptor, or neutrophil gelatinase-associated lipocalin (NGAL) receptor (NGALR). It functions as a cell surface receptor for lipocalin-2 (LCN2), also called NGAL or 24p3, which plays a key role in iron homeostasis and transport. LCN2 is a secreted protein of the lipocalin family that induces apoptosis in some types of cells and inhibits bacterial growth by sequestration of the iron-laden bacterial siderophore. Over-expressions of NGAL and NGALR have been found to be correlated with unfavorable clinicopathologic features and poor prognosis of patients with hepatocellular carcinoma. SLC22A17 is a member of the SLC22 family of organic cation/anion/zwitterion transporters, which includes organic cation transporters (OCTs/OCTNs) and organic anion transporters (OATs). It 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.

Class 1 and Class 2 Glucose transporters (GLUTs) of the Major Facilitator Superfamily; This subfamily includes Class 1 and Class 2 glucose transporters (GLUTs) including Solute carrier family 2, facilitated glucose transporter member 1 (SLC2A1, also called glucose transporter type 1 or GLUT1), SLC2A2-5 (GLUT2-5), SLC2A7 (GLUT7), SLC2A9 (GLUT9), SLC2A11 (GLUT11), SLC2A14 (GLUT14), and similar proteins. GLUTs are a family of proteins that facilitate the transport of hexoses such as glucose and fructose. There are fourteen GLUTs found in humans; they display different substrate specificities and tissue expression. They have been categorized into three classes based on sequence similarity: Class 1 (GLUTs 1-4, 14); Class 2 (GLUTs 5, 7, 9, and 11); and Class 3 (GLUTs 6, 8, 10, 12, and HMIT). GLUTs 1-5 are the most thoroughly studied and are well-established as glucose and/or fructose transporters in various tissues and cell types. GLUT proteins are comprised of about 500 amino acid residues, possess a single N-linked oligosaccharide, and have 12 transmembrane segments. They belong to the Glucose transporter -like (GLUT-like) family of the Major Facilitator Superfamily (MFS) of membrane transport proteins. MFS proteins are thought to function through a single substrate binding site, alternating-access mechanism involving a rocker-switch type of movement.

Organic anion transporters of the Major Facilitator Superfamily of transporters; Organic anion transporters (OATs) generally display broad substrate specificity and they facilitate the exchange of extracellular with intracellular organic anions (OAs). Several OATs have been characterized including OAT1-10 and urate anion exchanger 1 (URAT1, also called SLC22A12). Many OATs occur in renal proximal tubules, the site of active drug secretion. OATs mediate the absorption, distribution, and excretion of a diverse array of environmental toxins, and clinically important drugs, including anti-HIV therapeutics, anti-tumor drugs, antibiotics, anti-hypertensives, and anti-inflammatories, and therefore is critical for the survival of the mammalian species. OAT falls into the SLC22 (solute carrier 22) family of 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.

Plant organic cation/carnitine transporters of the Major Facilitator Superfamily of transporters; Plant organic cation/carnitine transporters (OCTs) are sequence-similar to their animal counterparts, which are broad-specificity transporters that play a critical role in the excretion and distribution of endogeneous organic cations and for the uptake, elimination and distribution of cationic drugs, toxins, and environmental waste products. Little is know about plant OCTs. In Arabidopsis, there are six genes belonging to this family that show distinct, organ-specific expression pattern of the individual genes. AtOCT1 has been found to affect root development and carnitine-related responses in Arabidopsis. AtOCT4, 5 and 6 are up-regulated during drought stress, AtOCT3 and 5 during cold stress and AtOCT5 and 6 during salt stress treatments. Plant OCTs belongs to the Solute carrier 22 (SLC22) family of organic cation/anion/zwitterion transporters of the Major Facilitator Superfamily (MFS) of membrane transport proteins. MFS proteins are thought to function through a single substrate binding site, alternating-access mechanism involving a rocker-switch type of movement.

10-46 3.31e-03

Solute carrier family 22 member 6 (also called Organic anion transporter 1) and similar transporters of the Major Facilitator Superfamily; This subfamily includes solute carrier family 22 member 6 (SLC22A6, also called organic anion transporter 1 or OAT1 or para-aminohippurate (PAH) transporter), SLC22A8 (or OAT3), and SLC22A20 (or OAT6). OAT1 and OAT3 are involved in the renal elimination of endogenous and exogenous organic anions (OAs). They function as OA exchangers, coupling the uptake of OAs against an electrochemical gradient with the efflux of intracellular dicarboxylates. SLC22A20 is an OA transporter that mediates the uptake of estrone sulfate. The OAT1-like subfamily belongs to the Solute carrier 22 (SLC22) family of organic cation/anion/zwitterion transporters of the Major Facilitator Superfamily (MFS) of membrane transport proteins. MFS proteins are thought to function through a single substrate binding site, alternating-access mechanism involving a rocker-switch type of movement.
