CC -!- FUNCTION: Functions as a sodium-dependent amino acid transporter.
CC Mediates the saturable, pH-sensitive and electrogenic cotransport of
CC neutral amino acids and sodium ions with a stoichiometry of 1:1. May
CC function in the transport of amino acids at the blood-brain barrier and
CC in the supply of maternal nutrients to the fetus through the placenta
CC (By similarity). {ECO:0000250}.
CC -!- ACTIVITY REGULATION: Inhibited by N-methyl-D-glucamine and choline.
CC {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250}; Multi-pass membrane
CC protein {ECO:0000250}. Note=Insulin promotes recruitment to the plasma
CC membrane from a pool localized in the trans-Golgi network or endosomes.
CC Enriched in the somatodendritic compartment of neurons, it is also
CC detected at the axonal shaft but excluded from the nerve terminal.
CC {ECO:0000250}.
CC -!- PTM: Polyubiquitination by NEDD4L regulates the degradation and the
CC activity of SLC38A2. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the amino acid/polyamine transporter 2 family.
CC {ECO:0000305}.
