Synonyms ATRC2; CAT-2; CAT2; HCAT2; Low affinity cationic amino acid transporter 2; SLC7A2; Solute carrier family 7 member 2
DT Family Amino Acid-Polyamine-Organocation (APC) Family
Cationic Amino Acid Transporter (CAT) Family
Tissue Specificity Expressed at high levels in the skeletalmuscle, placenta and ovary. Expressed at intermediate levels inthe liver and pancreas and at low levels in the kidney and heart.
Function This transporter functions as permease involved in the transport of the cationic amino acids (arginine, lysine and ornithine); the affinity for its substrates differs between isoforms created by alternative splicing. Isoform 1 functions as permease that mediates the transport of the cationic amino acids (arginine, lysine and ornithine), and it has much higher affinity for arginine than isoform 2. Isoform 2 functions as low-affinity, high capacity permease involved in the transport of the cationic amino acids (arginine, lysine and ornithine).
Endogenous Substrate(s) Arginine; Lysine; Ornithine
