    Summary
    Enables glutamine synthetase activity. Involved in glutamine biosynthetic process. Located in nuclear periphery. Human ortholog(s) of this gene implicated in congenital glutamine deficiency; epilepsy (multiple); heart disease; and neurodegenerative disease (multiple). Orthologous to human GLUL (glutamate-ammonia ligase). [provided by Alliance of Genome Resources, Nov 2024]

    What's a GeneRIF?
    1. The results point to the stress-related proteins Ahp1, Yhb1 and Oye2, as well as Gln1 and Kes1 as putative candidates for being evaluated as biomarkers for diagnostic assays of S. cerevisiae infections.
      Title: Immunoproteomic profiling of Saccharomyces cerevisiae systemic infection in a murine model.
    2. Comparative structure analysis suggests that citrate binding could induce structural fluctuation of the segment Leu293-Ala300, which may serve the role of guarding the glutamate entrance to the active sites.
      Title: Crystal structure of Saccharomyces cerevisiae glutamine synthetase Gln1 suggests a nanotube-like supramolecular assembly.
    3. Data suggested that Gpx3 protects GS from non-enzymatic proteolysis, thereby contributing to cell homeostasis when cell is exposed to oxidative stress.
      Title: Glutathione peroxidase 3 of Saccharomyces cerevisiae suppresses non-enzymatic proteolysis of glutamine synthetase in an activity-independent manner.

    • Glutamine synthetase (GS); synthesizes glutamine from glutamate and ammonia; with Glt1p, forms the secondary pathway for glutamate biosynthesis from ammonia; expression regulated by nitrogen source and by amino acid limitation; forms filaments of back-to-back stacks of cylindrical homo-decamers at low pH, leading to enzymatic inactivation and storage during states of advanced cellular starvation; relocalizes from nucleus to cytoplasmic foci upon DNA replication stress
