Target

  • FunctionThis enzyme has 2 functions: it catalyzes the production of glutamine and 4-aminobutanoate (gamma-aminobutyric acid, GABA), the latter in a pyridoxal phosphate-independent manner (By similarity). Essential for proliferation of fetal skin fibroblasts.
  • Involvement in diseaseDefects in GLUL are the cause of congenital systemic glutamine deficiency (CSGD) [MIM:610015]. CSGD is a rare developmental disorder with severe brain malformation resulting in multi-organ failure and neonatal death. Glutamine is largely absent from affected patients serum, urine and cerebrospinal fluid.
  • Sequence similaritiesBelongs to the glutamine synthetase family.
  • Developmental stageExpressed during early fetal stages.
  • Cellular localizationCytoplasm. Mitochondrion.

Anti-Glutamine Synthetase antibody images

  • ab93439 staining Glutamine Synthetase in zebrafish retina sections by IHC-Fr. The tissue was fixed with paraformaldehyde and an antigen retrieval step was performed with sodium citrate pH 6. Blocking of the sample was done with 5% BSA in PBS containing 01% Tween 20 and 0.5% Triton X, for 60 minutes at 23°C, followed by staining with ab93439 at 1/100 in blocking solution for 16h at 4°C. An alexa 647 conjugated goat anti-rabbit polyclonal antibody at 1/1000 was used as the secondary antibody. Nuclei are stained in blue with DAPI. Glutamine Synthetase expression can be observed in Muller cells (in purple).

    Developed using the ECL technique

    Performed under reducing conditions.

    Predicted band size : 42 kDa
    Observed band size : 45 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 200 kDa. We are unsure as to the identity of these extra bands.

    Exposure time : 30 seconds
  • IHC-FoFr image of Glutamine Synthetase staining on rat brain sections using ab93439 (1:1000). The sections used came from animals perfused fixed with Paraformaldehyde 4% with 15% of a solution of saturated picric acid, in phosphate buffer 0.1M. Following postfixation in the same fixative overnight, the brains were cryoprotected in sucrose 30% overnight. Brains were then cut using a cryostat and the immunostainings were performed using the ‘free floating’ technique.
