This gene encodes a protein that belongs to a family of light subunits of amino acid transporters. This protein plays a role in the high-affinity and sodium-independent transport of cystine and neutral and dibasic amino acids, and appears to function in the reabsorption of cystine in the kidney tubule. Mutations in this gene cause non-type I cystinuria, a disease that leads to cystine stones in the urinary system due to impaired transport of cystine and dibasic amino acids. Alternate transcript variants, which encode the same protein, have been found for this gene. [provided by RefSeq, Jul 2011]
GeneCards Summary for SLC7A9 Gene
SLC7A9 (Solute Carrier Family 7 Member 9) is a Protein Coding gene. Diseases associated with SLC7A9 include Cystinuria and Ureteral Disease. Among its related pathways are Transport of glucose and other sugars, bile salts and organic acids, metal ions and amine compounds and Collagen chain trimerization. Gene Ontology (GO) annotations related to this gene include peptide antigen binding and antiporter activity. An important paralog of this gene is SLC7A5.
UniProtKB/Swiss-Prot Summary for SLC7A9 Gene
Involved in the high-affinity, sodium-independent transport of cystine and neutral and dibasic amino acids (system b(0,+)-like activity). Thought to be responsible for the high-affinity reabsorption of cystine in the kidney tubule.
