Target

  • Function

    This 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 disease

    Defects 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 similarities

    Belongs to the glutamine synthetase family.

  • Developmental stage

    Expressed during early fetal stages.

  • Cellular localization

    Cytoplasm. Mitochondrion.

      Lanes 1- 2: Merged signal (red and green). Green - ab197024 observed at 42 kDa. Red - Anti-alpha Tubulin antibody [DM1A] - Loading Control (ab7291) observed at 50 kDa.

       ab197024 was shown to react with Glutamine Synthetase in wild-type HeLa cells in western blot. Loss of signal was observed when knockout cell line ab261737 (knockout cell lysate ab256930) was used. Wild-type HeLa and GLUL knockout HeLa cell lysates were subjected to SDS-PAGE. ab197024 and Anti-alpha Tubulin antibody [DM1A] - Loading Control (ab7291) overnight at 4°C at a 1 in 1000 Dilution and a 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye®800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye®680RD) preadsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.

      ab197024 was shown to specifically react with Glutamine Synthetase in wild-type HAP1 cells as signal was lost in Glutamine Synthetase knockout cells. Wild-type and Glutamine Synthetase knockout samples were subjected to SDS-PAGE. ab197024 and ab18058 (Mouse anti-Vinculin loading control) were incubated overnight at 4°C at 1/1000 dilution and 1/20000 dilution respectively.
