SLC1A5 and cancer: Alanine-Serine-Cysteine Transporter 2 (ASCT2), a sodium (Na+)-dependent transmembrane transporter encoded by the solute carrier family 1 member 5 (SLC1A5) gene, mediates the cellular uptake of glutamine and other neutral amino acids and is considered to be a primary glutamine transporter in cancer cells (11, 12).
