Sodium-dependent neutral amino acid transporter B(0)AT2 (SLC6A15)

Functions as a sodium-dependent neutral amino acid transporter. Exhibits preference for the branched-chain amino acids, especially leucine, valine and isoleucine and methionine.

Mediates the saturable, pH-sensitive and electrogenic cotransport of proline and sodium ions with a stoichiometry of 1:1. May have a role as transporter for neurotransmitter precursors into neurons.
