Detail: Structure Info

Synonyms ATA1; Amino acid transporter A1; N-system amino acid transporter 2; NAT2; SLC38A1; SNAT1; Solute carrier family 38 member 1; System A amino acid transporter 1; System N amino acid transporter 1
DT Family Amino Acid/Auxin Permease (AAAP) Family ;
Tissue Specificity Expressed in the cerebral cortex by pyramidaland GABAergic neurons, astrocytes and other non-neuronal cells (atprotein level). Expressed in placenta, heart, lung, skeletalmuscle, spleen, stomach and testis.
Function This sodium-dependent amino acid transporter mediates the saturable, pH-sensitive and electrogenic cotransport of glutamine and sodium ions with a stoichiometry of 1:1. May also transport small zwitterionic and aliphatic amino acids with a lower affinity. May supply glutamatergic and GABAergic neurons with glutamine which is required for the synthesis of the neurotransmitters glutamate and GABA.
Disease(s) Short bowel syndrome [ICD-11: KB89.1]
Endogenous Substrate(s) Glutamine; Sodium ions; Zwitterionic amino acids; Aliphatic amino acids
