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.

Notes

GLS1 Inhibitor Screening Kit is a plate-based fluorometric kit for screening human GLS1 inhibitors. The hydrolysis of glutamine by glutaminase forms glutamate and ammonia. Glutamate, in the presence of a developer and enzyme mix, converts a non-fluorescent probe to a fluorescent product via an enzymatic reaction. A well-known Glutaminase inhibitor - CB-839 is provided as an inhibitor control.

This kit is sensitive and is a specific assay for screening GLS1 inhibitors.

This product is manufactured by BioVision, an Abcam company and was previously called K479 Glutaminase (GLS1) Inhibitor Screening Kit (Fluorometric). K479-100 is the same size as the 100 test size of ab283389.

Activity summary

Glutaminase also known as GLS or GLS1 is an enzyme that catalyzes the conversion of glutamine to glutamate an important step in cellular nitrogen and energy metabolism. This enzyme weighs approximately 65 kDa and is expressed in various tissues particularly in the brain kidney and liver. Glutaminase exists in two isoforms GLS1 and GLS2 with GLS1 being the more studied due to its role in cancer metabolism.

Biological function summary

Glutaminase plays a central role in cellular processes by facilitating the production of glutamate which is an important neurotransmitter in the brain and a precursor for the synthesis of gamma-aminobutyric acid (GABA). It is not part of a larger complex but acts independently in the mitochondrial matrix where it performs the glutaminase reaction. The activity of this enzyme is monitored closely because it affects multiple cellular functions and has implications in many diseases.

Pathways

Glutaminase is instrumental in the glutaminolysis and tricarboxylic acid (TCA) cycles. These pathways are essential for cellular energy production and biosynthesis. GLS1 activity influences other proteins such as alanine transaminase (ALT) and aspartate transaminase (AST) which also play roles in amino acid metabolism and energy production. Glutaminase inhibitors have been explored as potential therapeutic agents by disrupting the glutaminolysis pathway in cancer cells leading to decreased tumor growth.

Associated diseases and disorders

Glutaminase has a significant link to cancer and neurodegenerative diseases. In cancer GLS1 activity is often upregulated as tumor cells require increased glutamine metabolism for growth and survival making GLS1 inhibitors a target in cancer therapy. Neurodegenerative disorders such as Alzheimer's disease also show altered glutamate levels implicating glutaminase in disease progression. These disorders highlight the enzyme's potential connections with proteins like NMDA receptors in the brain where glutamate acts as a neurotransmitter affecting synaptic activity.
