S38A2_HUMAN (UniProt)

Gene names: SLC38A2, ATA2, KIAA1382, SAT2, SNAT2
Protein names and data: S38A2_HUMAN, Full=Sodium-coupled neutral amino acid transporter 2, Full=Amino acid transporter A2;Full=Protein 40-9-1;Full=Solute carrier family 38 member 2;Full=System A amino acid transporter 2;Full=System A transporter 1;Full=System N amino acid transporter 2; Length: 506 a.a., Mass: 56026 Da,
fasta formatted sequence

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
Cellular location: Cell membrane; Multi-pass membrane protein. 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
Tissue specificity: Ubiquitously expressed. Widely expressed in the central nervous system with higher concentrations in caudal regions. Expressed by glutamatergic and GABAergic neurons together with astrocytes and other non-neuronal cells in the cerebral cortex (at protein level)
