loss of glutamine synthetase activity either inherited or induced through L-methionine sulfoximine leads to an upregulation of the glutamine synthetase protein but not of the glutamine synthetase mRNA and results in a significant drop in the proliferation rate but has no effect on apoptosis. Exogenous glutamine does not influence the rate of apoptosis but increases proliferation rates of the fetal but not the mature fibroblasts

the role of GS in humans 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, one of the enzymes is responsible for the removal of ammonia

the enzyme acts as an acetyl-CoA independent acetyltransferase mediating the transfer of acetyl group(s) from polyphenolic acetates to certain functional proteins in mammalian cells, e.g. protein acetylation by a model acetoxy drug 7, 8-diacetoxy-4-methylcoumarin, or acetylation and inhibition of glutathione transferase using polyphenolic actetate, substrate specificity, overview. The TAase activity of MTAase is independent of the catalytic activity of the glutamine synthetase
