- Function
- Associates with SLC3A1 to form a functional transporter complex that mediates the electrogenic exchange between cationic amino acids and neutral amino acids, with a stoichiometry of 1:1 (PubMed:8663357, PubMed:16825196, PubMed:32817565, PubMed:32494597). Has system b(0,+)-like activity with high affinity for extracellular cationic amino acids and L-cystine and lower affinity for intracellular neutral amino acids (PubMed:8663357, PubMed:16825196, PubMed:32494597). Substrate exchange is driven by ... (Source: Uniprot)

HI Disease:
- cystinuria Monarch
HI Evidence Comments:
Cystinuria is a metabolic disorder of impaired cystine and dibasic amino acid transport caused by mutations in either the SLC3A1 and/or SLC7A9 genes (both genes encode components of the transporter complex rBAT/b0,+AT). Most affected patients have bi-allelic mutations leading to impaired renal reabsorption of cystine, causing formation of calculi (stones) in the renal and urinary tracts; rarely this may lead to renal failure.
Heterozygous SLC7A9 mutation carriers with cystinuria are also reported in the literature (2 deletions reported by Schmidt et al., 2003, PMID 14531788). Such mutations are considered to be dominant-acting, but with incomplete penetrance. The mechanism of pathogenicity in these cases is unknown.
