  • Function
    Sodium-dependent amino acids transporter that has a broad substrate specificity, with a preference for zwitterionic amino acids. It accepts as substrates all neutral amino acids, including glutamine, asparagine, and branched-chain and aromatic amino acids, and excludes methylated, anionic, and cationic amino acids. May also be activated by insulin. Through binding of the fusogenic protein syncytin-1/ERVW-1 may mediate trophoblasts syncytialization, the spontaneous fusion of their plasma membranes, an essential process in placental development (PubMed:10708449, PubMed:23492904). Acts as a cell surface receptor for feline endogenous virus RD114, baboon M7 endogenous virus and type D simian retroviruses (PubMed:10051606, PubMed:10196349).
  • Tissue specificity
    Placenta, lung, skeletal muscle, kidney, pancreas, and intestine.
  • Sequence similarities
    Belongs to the dicarboxylate/amino acid:cation symporter (DAACS) (TC 2.A.23) family. SLC1A5 subfamily.
  • Cellular localization
    Cell membrane. Melanosome. Identified by mass spectrometry in melanosome fractions from stage I to stage IV.

  • Anti-SLC1A5 antibody (ab84903) at 1 µg/ml + Jurkat (Human T cell lymphoblast-like cell line) Whole Cell Lysate at 10 µg

    Goat polyclonal to Rabbit IgG - H&L - Pre-Adsorbed (HRP) at 1/3000 dilution

    Developed using the ECL technique.

    Performed under reducing conditions.

    Predicted band size: 56 kDa
    Observed band size: 52 kDa
    why is the actual band size different from the predicted?
    Additional bands at: 45 kDa, 97 kDa. We are unsure as to the identity of these extra bands.

    Exposure time: 20 minutes

    The 52 kDa band observed is comparable to the molecular weight seen with other commercially available antibodies to Human Neutral amino acid transporter B (SLC1A5).
  • ICC/IF image of ab84903 stained Hek293 cells. The cells were 4% PFA fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab84903, 5µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM. This antibody also gave a positive result in 4% PFA fixed (10 min) HepG2 and MCF7 cells at 5µg/ml, and in 100% methanol fixed (5 min) Hek293, HepG2 and MCF7 cells at 5µg/ml.
  • IHC image of SLC1A5 staining in human normal kidney formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab84903, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.
