Entrez Gene Summary for SLC15A1 Gene

  • This gene encodes an intestinal hydrogen peptide cotransporter that is a member of the solute carrier family 15. The encoded protein is localized to the brush border membrane of the intestinal epithelium and mediates the uptake of di- and tripeptides from the lumen into the enterocytes. This protein plays an important role in the uptake and digestion of dietary proteins. This protein also facilitates the absorption of numerous peptidomimetic drugs. [provided by RefSeq, Apr 2010]

GeneCards Summary for SLC15A1 Gene

SLC15A1 (Solute Carrier Family 15 (Oligopeptide Transporter), Member 1) is a Protein Coding gene. Among its related pathways are Transport of glucose and other sugars, bile salts and organic acids, metal ions and amine compounds and Protein digestion and absorption. GO annotations related to this gene include proton-dependent oligopeptide secondary active transmembrane transporter activity and peptide:proton symporter activity. An important paralog of this gene is SLC15A3.

UniProtKB/Swiss-Prot for SLC15A1 Gene
