Solute carrier family 7 (cationic amino acid transporter, y+ system), member 9 also known as SLC7A9 is a protein which in humans is encoded by the SLC7A9 gene.[1]
Function
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.[1] The protein associates with the protein coded for by SLC3A1.[2]
Clinical significance
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.[1]
