Detail: Structure Info

Synonyms ATA3; Amino acid transporter A3; NAT3; Na(+)-coupled neutral amino acid transporter 4; PAAT; SLC38A4; SNAT4; Solute carrier family 38 member 4; System A amino acid transporter 3; System N amino acid transporter 3
DT Family Amino Acid/Auxin Permease (AAAP) Family ;
Tissue Specificity Detected in embryonic and adult liver, and atlower levels in adult muscle, kidney and pancreas. Detected inplacenta syncytiotrophoblasts throughout gestation. Detected infetal blood vessels.
Function This sodium-dependent transporter mediates electrogenic symport of neutral amino acids and sodium ions. Has a broad specificity, with a preference for Ala, followed by His, Cys, Asn, Ser, Gly, Val, Thr, Gln and Met. May mediate sodium-independent transport of cationic amino acids, such as Arg and Lys. Amino acid uptake is pH-dependent, with low transport activities at pH 6. 5, intermediate at pH 7. 0 and highest between pH 7. 5 and 8. 5.
Disease(s) Short bowel syndrome [ICD-11: KB89.1]
