Protein attributes
| Sequence length | 664 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Actively transports glucose into cells by Na+ cotransport with a Na+ to glucose coupling ratio of 2:1. Efficient substrate transport in mammalian kidney is provided by the concerted action of a low affinity high capacity and a high affinity low capacity Na+/glucose cotransporter arranged in series along kidney proximal tubules. |
| Subcellular location | |
| Tissue specificity | Expressed mainly in intestine and kidney. |
| Post-translational modification | N-glycosylation is not necessary for the cotransporter function. |
| Involvement in disease | Congenital glucose/galactose malabsorption (GGM) [MIM:606824]: Intestinal monosaccharide transporter deficiency. It is an autosomal recessive disorder manifesting itself within the first weeks of life. It is characterized by severe diarrhea and dehydration which are usually fatal unless glucose and galactose are eliminated from the diet. |
| Sequence similarities | Belongs to the sodium:solute symporter (SSF) (TC 2.A.21) family. [View classification] |
