Entrez Gene Summary for SLC22A3 Gene

  • Polyspecific organic cation transporters in the liver, kidney, intestine, and other organs are critical for elimination of many endogenous small organic cations as well as a wide array of drugs and environmental toxins. This gene is one of three similar cation transporter genes located in a cluster on chromosome 6. The encoded protein contains twelve putative transmembrane domains and is a plasma integral membrane protein. [provided by RefSeq, Jul 2008]

GeneCards Summary for SLC22A3 Gene

SLC22A3 (Solute Carrier Family 22 (Organic Cation Transporter), Member 3) is a Protein Coding gene. Among its related pathways are Metabolism and Transport of glucose and other sugars, bile salts and organic acids, metal ions and amine compounds. GO annotations related to this gene include organic cation transmembrane transporter activity and toxin transporter activity. An important paralog of this gene is SLC22A12.

UniProtKB/Swiss-Prot for SLC22A3 Gene

  • Mediates potential-dependent transport of a variety of organic cations. May play a significant role in the disposition of cationic neurotoxins and neurotransmitters in the brain.
