SLC7A9 (solute carrier family 7 member 9)

Gene

• Entrez ID: 11136
• Gene name: Solute carrier family 7 member 9
• Gene symbol: SLC7A9
• Synonyms (NCBI Gene): BAT1, CSNU3
• Chromosome: 19
• Chromosome location: 19q13.11
• Summary: 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 t
