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). 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).

Activity summary

Glutamine synthetase also known as glutamine s synthetase or glnA is an enzyme that catalyzes the ATP-dependent conversion of glutamate and ammonia into glutamine. This reaction plays an important role in nitrogen metabolism. Glutamine synthetase has a molecular weight of approximately 620 kDa and forms a multimeric structure commonly seen in bacteria plants and animal tissues with significant expression in the brain liver and kidneys.

Biological function summary

This enzyme supports the detoxification of ammonia by incorporating it into glutamine an essential amino acid and nitrogen donor. Glutamine synthetase operates independently rather than as part of a larger protein complex. It assists in maintaining cellular nitrogen balance and facilitates the synthesis of proteins and other nitrogen-containing molecules. Glutamine peptides serve vital roles in cellular processes underlining the significance of their synthesis.

Pathways

Glutamine synthetase integrates into the glutamate and glutamine cycle between neurons and glial cells highlighting its part in neurotransmitter metabolism. It also features prominently in the urea cycle influencing nitrogen disposal in organisms. Glutamine synthetase interacts with glutaminase which assists in transforming glutamine back to glutamate maintaining a balance of nitrogenous compounds within these pathways.

Associated diseases and disorders

Glutamine synthetase abnormalities link to hepatic encephalopathy and neurodegenerative disorders such as Alzheimer's disease. Altered enzyme expression contributes to increased ammonia levels adversely affecting brain function. In Alzheimer's disease connections with tau and amyloid-beta proteins suggest a link between glutamine synthetase activity and neurotoxic events. Understanding these interactions may offer insights into therapeutic approaches for these conditions.

    IHC image of Glutamine Synthetase staining in a section of formalin-fixed paraffin-embedded normal rat liver performed on a Leica Biosystems BOND® RX instrument. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6, epitope retrieval solution 1) for 20mins. The section was then incubated with ab73593, 1 ug/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX. The inset secondary-only control image is taken from an identical assay without primary antibody.
    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
