CC -!- FUNCTION: Glutamine synthetase that catalyzes the ATP-dependent
CC conversion of glutamate and ammonia to glutamine (By similarity). Its
CC role depends on tissue localization: in the brain, it regulates the
CC levels of toxic ammonia and converts neurotoxic glutamate to harmless
CC glutamine, whereas in the liver, it is one of the enzymes responsible
CC for the removal of ammonia (By similarity). Essential for proliferation
CC of fetal skin fibroblasts. Independently of its glutamine synthetase
CC activity, required for endothelial cell migration during vascular
CC development: acts by regulating membrane localization and activation of
CC the GTPase RHOJ, possibly by promoting RHOJ palmitoylation. May act as
CC a palmitoyltransferase for RHOJ: able to autopalmitoylate and then
CC transfer the palmitoyl group to RHOJ (By similarity).
