Protein
Sodium-coupled neutral amino acid transporter 3
Function
Sodium-dependent amino acid/proton antiporter. Mediates electrogenic cotransport of glutamine and sodium ions in exchange for protons. Also recognizes histidine, asparagine and alanine. May mediate amino acid transport in either direction under physiological conditions. May play a role in nitrogen metabolism and synaptic transmission.
Similarity
Belongs to the amino acid/polyamine transporter 2 family.
