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 Hypoascorbemia. Among its related pathways are Metabolism and PAK Pathway. Gene Ontology (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

  • Sodium/ascorbate cotransporter. Mediates electrogenic uptake of vitamin C, with a stoichiometry of 2 Na(+) for each ascorbate.
