Solute carrier families 5 and 6-like; solute binding domain; This superfamily includes the solute-binding domain of SLC5 proteins (also called the sodium/glucose cotransporters or solute sodium symporters), SLC6 proteins (also called the sodium- and chloride-dependent neurotransmitter transporters or Na+/Cl--dependent transporters), and nucleobase-cation-symport-1 (NCS1) transporters. SLC5s co-transport Na+ with sugars, amino acids, inorganic ions or vitamins. SLC6s include Na+/Cl--dependent plasma membrane transporters for the monoamine neurotransmitters serotonin, dopamine, and norepinephrine, and the amino acid neurotransmitters GABA and glycine. NCS1s are essential components of salvage pathways for nucleobases and related metabolites; their known substrates include allantoin, uracil, thiamine, and nicotinamide riboside. Members of this superfamily are important in human physiology and disease. They contain a functional core of 10 transmembrane helices (TMs): an inverted structural repeat, TMs1-5 and TMs6-10; TMs numbered to conform to the SLC6 Aquifex aeolicus LeuT.

Na(+)/glucose cotransporter SGLT1;solute binding domain; Human SGLT1 (hSGLT1) is a high-affinity/low-capacity glucose transporter, which can also transport galactose. In the transport mechanism, two Na+ ions first bind to the extracellular side of the transporter and induce a conformational change in the glucose binding site. This results in an increased affinity for glucose. A second conformational change in the transporter follows, bringing the Na+ and glucose binding sites to the inner surface of the membrane. Glucose is then released, followed by the Na+ ions. In the process, hSGLT1 is also able to transport water and urea and may be a major pathway for transport of these across the intestinal brush-border membrane. hSGLT1 is encoded by the SLC5A1 gene and expressed mostly in the intestine, but also in the trachea, kidney, heart, brain, testis, and prostate. The WHO/UNICEF oral rehydration solution (ORS) for the treatment of secretory diarrhea contains salt and glucose. The glucose, along with sodium ions, is transported by hSGLT1 and water is either co-transported along with these or follows by osmosis. Mutations in SGLT1 are associated with intestinal glucose galactose malabsorption (GGM). Up-regulation of intestinal SGLT1 may protect against enteric infections. SGLT1 is expressed in colorectal, head and neck, and prostate tumors. Epidermal growth factor receptor (EGFR) functions in cell survival by stabilizing SGLT1, and thereby maintaining intracellular glucose levels. SGLT1 is predicted to have 14 membrane-spanning regions. This subgroup belongs to the solute carrier 5 (SLC5)transporter family.

Human SMCT1 (hSMCT1, also called AIT) is encoded by the tumor suppressor gene SLC5A8. SMCT1 is expressed in the colon, small intestine, kidney, thyroid gland, retina, and brain. SMCT1 may contribute to the intestinal/colonic and oral absorption of monocarboxylate drugs. It also mediates iodide transport from thyrocyte into the colloid lumen in thyroid gland and, through transporting L-lactate and ketone bodies, helps maintain the energy status and the function of neurons. SMCT2 is a low-affinity transporter for short-chain fatty acids, lactate, pyruvate, and nicotinate. hSMCT2 is encoded by the SLC5A12 gene.

Human SMCT1 (hSMCT1, also called AIT) is encoded by the tumor suppressor gene SLC5A8. Its expression is under the control of the C/EBP transcription factor. Its tumor-suppressive role is related to uptake of butyrate, propionate, and pyruvate, these latter are inhibitors of histone deacetylases. SMCT1 is expressed in the colon, small intestine, kidney, thyroid gland, retina, and brain. SMCT1 may contribute to the intestinal/colonic and oral absorption of monocarboxylate drugs. SMCT1 also mediates iodide transport from thyrocyte into the colloid lumen in thyroid gland and through transporting l-lactate and ketone bodies helps maintain the energy status and the function of neurons. In the kidney its expression is limited to the S3 segment of the proximal convoluted tubule (in contrast to the low-affinity monocarboxylate transporter SMCT2, belonging to a different family, which is expressed along the entire length of the tubule). In the retina, SMCT1 and SMCT2 may play a differential role in monocarboxylate transport in a cell type-specific manner, SMCT1 is expressed predominantly in retinal neurons and in retinal pigmented epithelial (RPE) cells. This subgroup belongs to the solute carrier 5 (SLC5) transporter family.

Uncharacterized bacterial solute carrier 5 subfamily; putative solute-binding domain; SLC5 (also called the sodium/glucose cotransporter family or solute sodium symporter family) is a family of proteins that co-transports Na+ with sugars, amino acids, inorganic ions or vitamins. Prokaryotic members of this family include Vibrio parahaemolyticus glucose/galactose (vSGLT), and Escherichia coli proline (PutP) and pantothenate (PutF) cotransporters. One member of the SLC5 family, human SGLT3, has been characterized as a glucose sensor and not a transporter. This subfamily belongs to the solute carrier 5 (SLC5) transporter family.

Na(+)/monocarboxylate cotransporter SMCT2 and related proteins; solute-binding domain; SMCT2 is a low-affinity transporter for short-chain fatty acids, lactate, pyruvate, and nicotinate. Human SMCT2 (hSMCT2) is encoded by the SLC5A12 gene. SMCT2 is expressed in the kidney, small intestine, skeletal muscle, and retina. In the kidney, it is expressed in the apical membrane of the proximal convoluted tubule, along the entire length of the tubule (in contrast to the high-affinity monocarboxylate transporter SMCT1, belonging to a different family, which is limited to the S3 segment of the tubule). SMCT2 may initiate lactate absorption in the early parts of the tubule. In the retina, SMCT1 and SMCT2 may play a differential role in monocarboxylate transport in a cell type-specific manner, SMCT2 is expressed exclusively in Muller cells. Nicotine transport by hSMCT2 is inhibited by several non-steroidal anti-inflammatory drugs. This subgroup belongs to the solute carrier 5 (SLC5) transporter family.

Na(+)/multivitamin cotransporter SMVT and related proteins; solute-binding domain; This multivitamin transporter SMVT (product of the SLC5A6 gene) transports biotin, pantothenic acid and lipoate, and is essential for mediating biotin uptake into mammalian cells. SMVT is expressed in the placenta, intestine, heart, brain, lung, liver, kidney and pancreas. Biotin may regulate its own cellular uptake through participation in holocarboxylase synthetase-dependent chromatin remodeling events at SMVT promoter loci. The cis regulatory elements, Kruppel-like factor 4 and activator protein-2, regulate the activity of the human SMVT promoter in the intestine. Glycosylation of the hSMVT is important for its transport function. This subgroup belongs to the solute carrier 5 (SLC5) transporter family.

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.

(labeled illustration) Four types of hits can be shown, as available,
for each region on the query sequence:

(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
