SLC7A9

b(0,+)-type amino acid transporter 1

b(0,+)-type amino acid transporter 1

Protein-coding gene in the species Homo sapiens

b(0,+)-type amino acid transporter 1, also known as b(0,+)AT1, is a protein which in humans is encoded by the SLC7A9 gene.[5]

Quick Facts SLC7A9, Identifiers ...

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.[5] The protein associates with the protein coded for by SLC3A1.[6]

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.[5]
