Summaries for SLC23A1 Gene

Entrez Gene Summary for SLC23A1 Gene

  • The absorption of vitamin C into the body and its distribution to organs requires two sodium-dependent vitamin C transporters. This gene encodes one of the two transporters. The encoded protein is active in bulk vitamin C transport involving epithelial surfaces. Previously, this gene had an official symbol of SLC23A2. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2008]

GeneCards Summary for SLC23A1 Gene

SLC23A1 (Solute Carrier Family 23 Member 1) is a Protein Coding gene. Diseases associated with SLC23A1 include Hypoascorbemia. Among its related pathways are Metabolism and Metabolism of water-soluble vitamins and cofactors. Gene Ontology (GO) annotations related to this gene include transporter activity and dehydroascorbic acid transmembrane transporter activity. An important paralog of this gene is SLC23A2.
