  • Immunofluorescence staining of HepG2 cells with CSB-PA887058LA01HU at 1:133, counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4°C. The secondary antibody was Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG(H+L).

Target Background

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.
Gene References into Functions
  1. This study assessed the relation of GLS2 downregulation in glioblastoma cells to its methylation and TP53 status. Aberrant methylation of CpG islands, appear to contribute to silencing of GLS2 in glioblastoma cells by a mechanism bypassing TP53 mutations. PMID: 26258493
  2. observe that while miR-23 is capable of down-regulating the shortened KGA 3'UTR, it has only minor impact on the full-length KGA 3'UTR, demonstrating that additional potent negative regulation of GLS expression exists beyond this single microRNA targeting site PMID: 27095025
  3. the crystal structure of full-length KGA and present a small-angle X-ray scattering model for full-length GLS2. These structures explain these proteins' compromised ability to assemble into catalytically active supra-tetrameric filaments, as previously shown for GAC. PMID: 28526749

  12. combination of negative modulation of glutaminase isoforms arising from GLS gene with the introduction of the GLS2 gene product, GAB, may in the future provide a useful means to curb glioblastoma growth in situ PMID: 24096582
  13. Epigenetic silencing of Gls2 via promoter hypermethylation is common in human liver and colon cancers. PMID: 24330717

  19. as a unique p53 target gene, GLS2 is a mediator of p53's role in energy metabolism and antioxidant defense, which can contribute to its role in tumor suppression PMID: 20378837
  20. Phosphate-activated glutaminase (GLS2) is a p53-inducible regulator of glutamine metabolism and reactive oxygen species PMID: 20351271
  21. results show L-type glutaminase is expressed in the brain with a nuclear localization and that this nuclear enzyme is catalytically active and displays kinetic properties different from both liver and kidney glutaminases PMID: 12163477
  22. Data describe the characterization of the human liver-type glutaminase (hLGA) gene. PMID: 12444921
  23. High levels of glutamate were produced by monocyte-derived macrophages infected with HIV-1 strains and inhibited by a glutaminase inhibitor and AZT thus implicating a glutamate-generating enzyme such as phosphate-activated mitochondrial glutaminase PMID: 14675161
  24. K glutaminase isoform is up-regulated with increased rates of proliferation in cancer cells, whereas prevalence of the L isoform seems to be related with resting or quiescent cell states PMID: 15496140
