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.

H(+)-myo-inositol cotransporter and similar transporters of the Major Facilitator Superfamily; This subfamily is composed of myo-inositol/inositol transporters and similar transporters from vertebrates, plant, and fungi. The human protein is called H(+)-myo-inositol cotransporter/Proton myo-inositol cotransporter (HMIT), or H(+)-myo-inositol symporter, or Solute carrier family 2 member 13 (SLC2A13). HMIT is classified as a Class 3 GLUT (glucose transporter) based on sequence similarity with GLUTs, but it does not transport glucose. It specifically transports myo-inositol and is expressed predominantly in the brain, with high expression in the hippocampus, hypothalamus, cerebellum and brainstem. HMIT may be involved in regulating processes that require high levels of myo-inositol or its phosphorylated derivatives, such as membrane recycling, growth cone dynamics, and synaptic vesicle exocytosis. Arabidopsis Inositol transporter 4 (AtINT4) mediates high-affinity H+ symport of myo-inositol across the plasma membrane. The HMIT-like subfamily belongs to the Glucose transporter -like (GLUT-like) family of the Major Facilitator Superfamily (MFS) of membrane transport proteins.

3.21e-13
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.

Synaptic vesicle glycoprotein 2C of the Major Facilitator Superfamily of transporters; Synaptic vesicle glycoprotein 2 (SV2) is a transporter-like integral membrane glycoprotein, with 12 transmembrane regions, expressed in vertebrates and is localized to synaptic and endocrine secretory vesicles. Three isoforms have been identified, SV2A, SV2B, and SV2C. SV2A and SV2B are widely expressed in the brain, while SV2C is more restricted to evolutionarily older brain. SV2 isoforms have been shown to be critical for the proper function of the central nervous system. SV2 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. SV2C exhibits enriched expression in several basal ganglia nuclei, and has been found to be involved in normal operation of the basal ganglia network and could be also be involved in system adaptation in basal ganglia pathological conditions. SV2C belongs to the Metazoan Synaptic Vesicle Glycoprotein 2 (SV2) and related small molecule transporter family (SV2-like) 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.

Oxalate:formate antiporter (OFA) and similar proteins of the Major Facilitator Superfamily of transporters; This subfamily is composed of Oxalobacter formigenes oxalate:formate antiporter (OFA or OxlT) and similar proteins. O. formigenes, a commensal found in the gut of animals and humans, plays an important role in clearing dietary oxalate from the intestinal tract, which is carried out by OFA/OxlT, an anion transporter that facilitates the exchange of divalent oxalate with monovalent formate, the product of oxalate decarboxylation. This exchange generates an electrochemical proton gradient and is the source of energy for ATP synthesis in this cell. The OFA-like subfamily belongs to the Monocarboxylate transporter -like (MCT-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.

This image shows a graphical summary of conserved domains identified on the query sequence.
The Show Concise/Full Display button at the top of the page can be used to select the desired level of detail: only top scoring hits
(labeled illustration) or all hits
(labeled illustration).
Domains are color coded according to superfamilies
to which they have been assigned. Hits with scores that pass a domain-specific threshold
(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
with the same color and shade of the domain or superfamily that provides the annotation. Mouse over the colored bars or triangles to see descriptions of the domains and features.
click on the bars or triangles to view your query sequence embedded in a multiple sequence alignment of the proteins used to develop the corresponding domain model.
The table lists conserved domains identified on the query sequence. Click on the plus sign (+) on the left to display full descriptions, alignments, and scores.
Click on the domain model's accession number to view the multiple sequence alignment of the proteins used to develop the corresponding domain model.
To view your query sequence embedded in that multiple sequence alignment, click on the colored bars in the Graphical Summary portion of the search results page,
or click on the triangles, if present, that represent functional sites (conserved features)
mapped to the query sequence.
Concise Display shows only the best scoring domain model, in each hit category listed below except non-specific hits, for each region on the query sequence.
(labeled illustration) Standard Display shows only the best scoring domain model from each source, in each hit category listed below for each region on the query sequence.
(labeled illustration) Full Display shows all domain models, in each hit category below, that meet or exceed the RPS-BLAST threshold for statistical significance.
(labeled illustration) Four types of hits can be shown, as available,
for each region on the query sequence:
specific hits meet or exceed a domain-specific e-value threshold
(illustrated example)
and represent a very high confidence that the query sequence belongs to the same protein family as the sequences use to create the domain model
non-specific hits
meet or exceed the RPS-BLAST threshold for statistical significance (default E-value cutoff of 0.01, or an E-value selected by user via the
advanced search options)
the domain superfamily to which the specific and non-specific hits belong
multi-domain models that were computationally detected and are likely to contain multiple single domains
