Description
High affinity cationic amino acid transporter 1 (CAT1), also called Solute carrier family 7 member 1(SLC7A1) or ATRC1, is a protein that in humans is encoded by the SLC7A1 gene. This gene is mapped to 13q12.3. It acts as a cationic amino acid transporter and as an ecotropic retrovirus receptor and plays a role in the Na+-independent y+ cationic amino acid transport system. CAT1 is a high-affinity, low capacity permease involved in the transport of the cationic amino acids(arginine, lysine and ornithine) in non-hepatic tissues
