Fungal Hexose transporter subfamily of the Major Facilitator Superfamily of transporters and similar proteins; The fungal hexose transporter (HXT) subfamily is comprised of functionally redundant proteins that function mainly in the transport of glucose, as well as other sugars such as galactose and fructose. Saccharomyces cerevisiae has 20 genes that encode proteins in this family (HXT1 to HXT17, GAL2, SNF3, and RGT2). Seven of these (HXT1-7) encode functional glucose transporters. Gal2p is a galactose transporter, while Rgt2p and Snf3p act as cell surface glucose receptors that initiate signal transduction in response to glucose, functioning in an induction pathway responsible for glucose uptake. Rgt2p is activated by high levels of glucose and stimulates expression of low affinity glucose transporters such as Hxt1p and Hxt3p, while Snf3p generates a glucose signal in response to low levels of glucose, stimulating the expression of high affinity glucose transporters such as Hxt2p and Hxt4p. Schizosaccharomyces pombe contains eight GHT genes (GHT1-8) belonging to this family. Ght1, Ght2, and Ght5 are high-affinity glucose transporters; Ght3 is a high-affinity gluconate transporter; and Ght6 high-affinity fructose transporter. The substrate specificities for Ght4, Ght7, and Ght8 remain undetermined. The HXT subfamily belongs 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.

It is expressed in pancreas, placenta, heart, lung, liver, brain, fat, muscle, and kidney. GLUT10 facilitates the transport of dehydroascorbic acid (DHA), the oxidized form of vitamin C, into mitochondria, and also increases cellular uptake of DHA, which in turn protects cells against oxidative stress. Loss-of-function mutations in SLC2A10 cause arterial tortuosity syndrome (ATS), an autosomal recessive connective tissue disorder characterized by twisting and lengthening of the major arteries, hypermobility of the joints, and laxity of skin.

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.

SV2 is a transporter-like protein that serves as the receptor for botulinum neurotoxin A (BoNT/A), one of seven neurotoxins produced by the bacterium Clostridium botulinum. BoNT/A blocks neurotransmitter release by cleaving synaptosome-associated protein of 25 kD (SNAP-25) within presynaptic nerve terminals. Also included in this family is synaptic vesicle 2 (SV2)-related protein (SVOP) and similar proteins.

Solute carrier organic anion transporters of the Major Facilitator Superfamily of transporters; Solute carrier organic anion transporters (SLCOs) are also called organic anion transporting polypeptides (OATPs) or SLC21 (Solute carrier family 21) proteins. They are sodium-independent transporters that mediate the transport of a broad range of endo- as well as xenobiotics. Their substrates are mainly amphipathic organic anions with a molecular weight of more than 300Da, although there are a few known neutral or positively charged substrates. These include drugs including statins, angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, antibiotics, antihistaminics, antihypertensives, and anticancer drugs. SLCOs/OATPs can be classified into 6 families (SLCO1-6 or OATP1-6) and each family may have subfamilies (e.g. OATP1A, OATP1B, OATP1C). Within the subfamilies, individual members are numbered according to the chronology of their identification and if there is already an ortholog known, they are given the same number. For example, the first SLCO identified, is rat OATP1A1 (encoded by the Slco1a1 gene). The second SLCO identified is the first human SLCO from the same subfamily and is called OATP1A2 (encoded by the SLCO1A2 gene). There are 11 human SLCOs/OATPs. SLCOs belong 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.
