UniProt ID
DT Family Major Facilitator Superfamily (MFS)
L-Amino Acid Transporter-3 (LAT3) Family
Function This sodium-independent transporter is for neutral amino acids and has narrower substrate selectivity compared to SLC7A5 and SLC7A8 and mainly transports branched-chain amino acids and phenylalanine. Plays a role in the development of human prostate cancer, from prostatic intraepithelial neoplasia to invasive prostate cancer.
