Protein

Sodium-coupled neutral amino acid transporter 2

Gene

Slc38a2

Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

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 supply of maternal nutrients to the fetus through the placenta.1 Publication

Enzyme regulationi

Inhibited by N-methyl-D-glucamine and choline.By similarity
