Na(+)/monocarboxylate cotransporter SMCT1 and related proteins; solute-binding domain; SMCT1 is a high-affinity transporter of various monocarboxylates including lactate and pyruvate, short-chain fatty acids, ketone bodies, nicotinate and its structural analogs, pyroglutamate, benzoate and its derivatives, and iodide. 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.

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.

Na(+)/glucose cotransporter SGLT2 and related proteins; solute-binding domain; Human SGLT2 (hSGLT2) is a high-capacity, low-affinity glucose transporter, that plays an important role in renal glucose reabsorption. It is encoded by the SLC5A2 gene and expressed almost exclusively in renal proximal tubule cells. Mutations in hSGLT2 cause Familial Renal Glucosuria (FRG), a rare autosomal defect in glucose transport. hSGLT2 is a major drug target for regulating blood glucose levels in diabetes. hSGLT2 is predicted to have 14 membrane-spanning regions. This subgroup belongs to the solute carrier 5 (SLC5) transporter family.

Na(+)/urea-polyamine cotransporter DUR3, and related proteins; solute-binding domain; Dur3 is the yeast plasma membrane urea transporter. Saccharomyces cerevisiae DUR3 also transports polyamine. The polyamine uptake of S. cerevisiae DUR3 is activated upon its phosphorylation by polyamine transport protein kinase 2 (PTK2). S. cerevisiae DUR3 also appears to play a role in regulating the cellular boron concentration. This subfamily belongs to the solute carrier 5 (SLC5) transporter family.

Na(+)/pantothenate cotransporters: PanF of Escherichia coli and related proteins; solute binding domain; PanF catalyzes the Na+-coupled uptake of extracellular pantothenate for coenzyme A biosynthesis in cells. This subfamily belongs to the solute carrier 5 (SLC5) transporter family.

Na(+)/myo-inositol cotransporter SMIT and related proteins; solute-binding domain; Human SMIT is a high-affinity myo-inositol transporter, and is expressed in brain, heart, kidney, and lung. Inhibition of myo-inositol uptake, through down-regulation of SMIT, may be a common mechanism of action of mood stabilizers, including lithium, carbamazepine, and valproate. SMIT is encoded by the SLC5A3 gene, which is a candidate gene for pathogenesis of nervous system dysfunction in Down syndrome (DS). The SNP, 21q22 near SLC5A3-MRPS6-KCNE2, has been associated with coronary heart disease, cardiovascular disease, and myocardial infarction. SMIT may also be involved in the pathogeneisis of congenital cataract. SMIT also plays roles in osteogenesis, bone formation, and bone mineral density determination. 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.

Click on the triangle to view details about the feature, including a multiple sequence alignment
of your query sequence and the protein sequences used to curate the domain model,
where hash marks (#) above the aligned sequences show the location of the conserved feature residues.

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:
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
