FEATURES

FAMILY

amino acid/polyamine transporter 2 family

DESCRIPTION

Also known as S38A4_PONAB, SLC38A4, ATA3, SNAT4. Sodium-dependent amino acid transporter. Mediates electrogenic symport of neutral amino acids and sodium ions. Has a broad specificity, with a preference for Ala, followed by Ser, Gly, Cys, Asn, Thr, Pro and Met. May mediate sodium-independent transport of cationic amino acids, such as Arg and Lys. Amino acid uptake is pH-dependent, with highest transport activity between pH 7.5 and 8.5 (By similarity).
