Recombinant Human Sodium-coupled neutral amino acid transporter 1 (SLC38A1), Truncated

Uniprot Id

Q9H2H9

Target Species

Human

Target Name

SLC38A1

Target Full Name

Sodium-coupled neutral amino acid symporter 1

Target Function

Functions as a 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.

Target Subcellular Location

Cell membrane; Multi-pass membrane protein.

Target Protein Families

Amino acid/polyamine transporter 2 family

Target Tissue Specificity

Expressed in the cerebral cortex by pyramidal and GABAergic neurons, astrocytes and other non-neuronal cells (at protein level). Expressed in placenta, heart, lung, skeletal muscle, spleen, stomach and testis.

Target Synonyms

Target Background

Amino acid transporters play essential roles in the uptake of nutrients, production of energy, chemical metabolism, detoxification, and neurotransmitter cycling. SLC38A1 is an important transporter of glutamine, an intermediate in the detoxification of ammonia and the production of urea. Glutamine serves as a precursor for the synaptic transmitter, glutamate (Gu et al., 2001 [PubMed 11325958]).
