Sodium-coupled neutral amino acid transporter 2 (Slc38a2)

Functions as a sodium-dependent amino acid transporter. Mediates the saturable, pH-sensitive and electrogenic cotransport of neutral amino acids and sodium ions with a stoichiometry of 1:1.

May function in the transport of amino acids at the blood- brain barrier and in the source of maternal nutrients to the fetus through the placenta. .
