General annotation (Comments)

Function

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 By similarity.

Enzyme regulation

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

Subcellular location

Cell membrane; Multi-pass membrane protein By similarity. Note: Insulin promotes recruitment to the plasma membrane from a pool localized in the trans-Golgi network or endosomes By similarity. Enriched in the somatodendritic compartment of neurons, it is also detected at the axonal shaft but excluded from the nerve terminal By similarity.

Post-translational modification

Polyubiquitination by NEDD4L regulates the degradation and the activity of SLC38A2 By similarity.

Sequence similarities

Belongs to the amino acid/polyamine transporter 2 family.
