Verification Image

Western blot analysis of extracts from MCF-7(lane 2(20μg), K562(lane 3(20μg), Jurkat(lane 4(20μg) and HEK293(lane 5(20μg) ) using Glutamine Synthetase (HY-P80408) Mouse mAb. Proteins were transferred to a PVDF membrane and blocked with 5% BSA in TBST for 2 hour at room temperature. The primary antibody (HY-P80408, 1/1000) and Loading control antibody (GAPDH, HY-P80954, 1/3000) was used in 5% BSA in TBST at 4°C overnight. Goat Anti-Mouse IgG-HRP Secondary Antibody (HY-P8004, 1/10,000) was used for 1 hour at room temperature.

Background

Function：Glutamine synthetase that catalyzes the ATP-dependent conversion of glutamate and ammonia to glutamine (PubMed:16267323, PubMed:30158707, PubMed:36289327). Its role depends on tissue localization: in the brain, it regulates the levels of toxic ammonia and converts neurotoxic glutamate to harmless glutamine, whereas in the liver, it is one of the enzymes responsible for the removal of ammonia (By similarity). Plays a key role in ammonium detoxification during erythropoiesis: the glutamine synthetase activity is required to remove ammonium generated by porphobilinogen deaminase (HMBS) during heme biosynthesis to prevent ammonium accumulation and oxidative stress (By similarity). Essential for proliferation of fetal skin fibroblasts (PubMed:18662667). Independently of its glutamine synthetase activity, required for endothelial cell migration during vascular development: acts by regulating membrane localization and activation of the GTPase RHOJ, possibly by promoting RHOJ palmitoylation (PubMed:30158707). May act as a palmitoyltransferase for RHOJ: able to autopalmitoylate and then transfer the palmitoyl group to RHOJ (PubMed:30158707). Plays a role in ribosomal 40S subunit biogenesis (PubMed:26711351). Through the interaction with BEST2, inhibits BEST2 channel activity by affecting the gating at the aperture in the absence of intracellular L-glutamate, but sensitizes BEST2 to intracellular L-glutamate, which promotes the opening of BEST2 and thus relieves its inhibitory effect on BEST2 (PubMed:36289327)

Subcellular Localization：Cytoplasm, cytosol; Microsome; Mitochondrion; Cell membrane; Lipid-anchor

Expression：
Tissue_specificity:Expression in endothelial cells

Induction:By glucocorticoids. Vitamin D and the Wnt signaling pathway inhibit its expression and activity (PubMed:18555765) . Glutamine synthase (GS) levels are regulated by a negative feedback mechanism where elevated glutamine levels stimulate GS ubiquitin-mediated proteasomal degradation (PubMed:26990986, PubMed:38579670)

Subunit：Decamer; composed of two pentamers (PubMed:18005987). Interacts with PALMD (By similarity). Interacts with RHOJ (PubMed:30158707). Interacts with BEST2; this interaction tethers a fraction of GLUL to the membrane, causing a decrease of cytosolic glutamine synthase (GS) activity and inhibits the chloride channel activity of BEST2 by affecting the gating at the aperture in the absence of intracellular glutamate (PubMed:36289327)

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
