    Summary
    Enables glutamine synthetase activity. Involved in L-glutamine biosynthetic process; phagocytosis; and positive regulation of mitochondrial fusion. Is active in mitochondrion. Is expressed in several structures, including adult head; adult heart; extraembryonic structure; larval somatic muscle cell; and visceral mesoderm derivative. 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, Dec 2024]
