Interaction of the neutral amino acid transporter ASCT2 with basic amino acids.
Title: Interaction of the neutral amino acid transporter ASCT2 with basic amino acids.
the selectivity profile of D-serine uptake in cultured rat hippocampal astrocytes is consistent with uptake mediated by both ASCT1 and ASCT2. Together these data suggest that SLC1A4 (ASCT1) may represent an important route of Na-dependent D-serine flux in the brain that has the ability to regulate extracellular D-serine and thereby NMDA receptor activity.
Title: D-Serine Is a Substrate for Neutral Amino Acid Transporters ASCT1/SLC1A4 and ASCT2/SLC1A5, and Is Transported by Both Subtypes in Rat Hippocampal Astrocyte Cultures.
Hypoxic exposure significantly increased SLC1A5 expression in neurovascular unit cells in vitro, but suppressed EAAT2 expression.
Title: Expression of Glutamate and Glutamine Transporter Proteins in Neurovascular Unit Cells In Vitro.
D-serine heteroexchange through ASC transporters, in particular low affinity ASCT2, is present in vivo and may constitute a key component in the regulation of D-serine extracellular concentration.
Title: In vivo D-serine hetero-exchange through alanine-serine-cysteine (ASC) transporters detected by microelectrode biosensors.
Basic amino acid transporter is localized in a punctuate manner following phorbol myristate acetate treatment when more pronounced bigger puncta are visible, indicating formation of bigger plasma membrane microdomains or astrocyte intracellular vesicles.
Title: Regulation of amino acid/carnitine transporter B 0,+ (ATB 0,+) in astrocytes by protein kinase C: independent effects on raft and non-raft transporter subpopulations.
The data demonstrated that the inhibition of ASCT2 by mercury compounds was due to covalent reactions with Cys residue(s) of the transporter.
Title: Inactivation by Hg2+ and methylmercury of the glutamine/amino acid transporter (ASCT2) reconstituted in liposomes: Prediction of the involvement of a CXXC motif by homology modelling.
Leptin controls active glutamine entry through reduction of both B(0)AT1 and ASCT2 protein trafficking to the apical plasma membrane and modulation of their gene expression.
Title: Luminal leptin inhibits L-glutamine transport in rat small intestine: involvement of ASCT2 and B0AT1.
ASCT2 accepts also glutamate as substrate and the membrane potential did not affect the glutamine/glutamine antiport whereas it stimulated about two fold the glutamine/glutamate antiport rate.
Title: The glutamine/amino acid transporter (ASCT2) reconstituted in liposomes: electrical nature of the glutamine/glutamate antiport.
the activity and expression of the ASCT2 transporter were considerably lower in the spontaneously hypertensive rats
Title: Underexpression of the Na+-dependent neutral amino acid transporter ASCT2 in the spontaneously hypertensive rat kidney.
The reconstituted glutamine/amino acid transporter functionally corresponds to the Asct2 protein.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
