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. Highly expressed in cytotrophoblast cells from term placenta. |
Post Translational Modifications | N-glycosylation plays an important role in the L-glutamine transport. |
Function | Symporter that cotransports short-chain neutral amino acids and sodium ions from the extraccellular to the intracellular side of the cell membrane. The transport is elctrogenic, pH dependent and driven by the Na(+) electrochemical gradient. Participates in the astroglia-derived glutamine transport into GABAergic interneurons for neurotransmitter GABA de novo synthesis. May also contributes to amino acid transport in placental trophoblasts. Also regulates synaptic plasticity. |
