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). . |

Structure 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). . |
Post-translational modification PTM: Palmitoylated; undergoes autopalmitoylation. .; PTM: Ubiquitinated by ZNRF1. . |

Involvement in disease Congenital systemic glutamine deficiency (CSGD) [MIM:610015]: Rare developmental disorder with severe brain malformation resulting in multi-organ failure and neonatal death. Glutamine is largely absent from affected patients serum, urine and cerebrospinal fluid. . Note=The disease is caused by variants affecting the gene represented in this entry. |
