  • Function
    Plays an important role in the regulation of glutamine catabolism. Promotes mitochondrial respiration and increases ATP generation in cells by catalyzing the synthesis of glutamate and alpha-ketoglutarate. Increases cellular anti-oxidant function via NADH and glutathione production. May play a role in preventing tumor proliferation.
  • Tissue specificity
    Highly expressed in liver. Expressed in brain and pancreas. Not observed in heart, placenta, lung, skeletal muscle and kidney. Expression is significantly reduced in hepatocellular carcinomas.
  • Sequence similarities
    Belongs to the glutaminase family.
    Contains 2 ANK repeats.

For TIGAR, we recommend any of the lysates shown in the western blot on the datasheet. We do not, however, have free samples.

For GLS2, ab113509 was validated for western blotting on blots of rat kidney lysate. We have this as ab29480.
