    basic FUNCTION
  • Na+ (and K+) dependent glutamate transporter, accepting as substrates all neutral amino acids, including glutamine, asparagine, and branched-chain and aromatic amino acids, and excludes methylated amino acids, anionic amino acids, and cationic amino acids
  • plays a key role in Gln transport controlling lung cancer cells metabolism, growth, and survival
  • ERVW1 and its receptor SLC1A45 are present in human gametes and localization and temporal appearance is consistent with a possible role in fusion between oocyte and sperm
  • is an important transporter of glutamine various cancer cells
  • N-linked glycosylation of SLC1A5 (ASCT2) transporter is critical for trafficking to membrane
  • involved in balancing the intracellular amino acid pool
  • plasma membrane transporter, responsible for mediating Na- dependent antiport of neutral amino acids
  • is responsible for the uptake of glutamine into cells, a major source of cellular energy and a key regulator of mammalian target of rapamycin (MTOR) activation
  • plays an important role in esophageal cancer
    a component
    small molecule other,
  • Cys is a potent competitive inhibitor of SLC1A5 but is not a substrate
  • protein
  • GJA1-mediated GJB1 and SLC1A5 interaction play important functional roles in trophoblast cell fusion
  • interactions of SLC5A1 with the scaffold protein PDZK1
  • SLC6A4 associates with SLC1A5, co-expressed with SLC6A4 in serotonergic neurons and involved in the transport of small neutral amino acids across the plasma membrane
  • PPARD directly regulated neutral amino acid transporter SLC1A5 and SLC2A1 gene transcription, leading to uptake of glucose and amino acid, activation of MTOR signaling and tumor progression
  • membrane-trafficked cargo molecule, sorted through a direct interaction with the PDZ domain of sorting nexin 27 (SNX27)
  • SLC1A5, a key glutamine transporter, is a novel TEAD1 target gene
  • TEAD1 promotes vascular smooth muscle cells (VSMCs) proliferation via transcriptional induction of SLC1A5, thereby activating MTOR signaling and promoting neointima formation
  • critical for activation of MTOR activity by amino acids, and is a transcriptional target of MYC

    Therapy target
    inhibition of esophageal cancer growth by targeting SLC1A5 could, therefore, be used as a preoperative therapy for esophageal cancer
    SLC1A5 could be a novel therapeutic target against KRAS-mutant colorectal cancer
