Summaries for SLC23A2 Gene

Entrez Gene Summary for SLC23A2 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 required transporters and the encoded protein accounts for tissue-specific uptake of vitamin C. Previously, this gene had an official symbol of SLC23A1. [provided by RefSeq, Jul 2008]

GeneCards Summary for SLC23A2 Gene

SLC23A2 (Solute Carrier Family 23 Member 2) is a Protein Coding gene. Diseases associated with SLC23A2 include scurvy. Among its related pathways are Metabolism and Metabolism of water-soluble vitamins and cofactors. GO annotations related to this gene include transporter activity and sodium-dependent multivitamin transmembrane transporter activity. An important paralog of this gene is SLC23A1.

UniProtKB/Swiss-Prot for SLC23A2 Gene
