Detail: Struture Info

Synonyms BAT1; CSNU3; SLC7A9; Solute carrier family 7 member 9; b(0,+)-type amino acid transporter 1; b(0,+)AT1
DT Family Amino Acid-Polyamine-Organocation (APC) Family
L-type Amino Acid Transporter (LAT) Family
Tissue Specificity Expressed in the brush border membrane in thekidney (at protein level). Kidney, small intestine, liver andplacenta.
Function This transporter thought to be responsible for the high-affinity reabsorption of cystine in the kidney tubule. Involved in the high-affinity, sodium-independent transport of cystine and neutral and dibasic amino acids (system b(0,+)-like activity).
Endogenous Substrate(s) Cystine; Neutral and dibasic amino acids
