Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
There is experimental evidence that it has the molecular function: glutamate-ammonia ligase activity.
There is experimental evidence that it is involved in the biological process: glutamine metabolic process; mitochondrion organization.
16 alleles are reported.
The phenotypes of these alleles are annotated with: embryonic somatic muscle; A1-7 dorsal oblique muscle 2; muscle attachment site.
It has 3 annotated transcripts and 3 annotated polypeptides.
Protein features are: Glutamine synthetase, beta-Grasp; Glutamine synthetase, catalytic domain; Glutamine synthetase/guanido kinase, catalytic domain.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of very high expression to a trough of moderately high expression.
Peak expression observed within 00-18 hour embryonic stages, at stages throughout the larval period, during early pupal stages.
