The gene atlastin is referred to in FlyBase by the symbol Dmel\atl (CG6668, FBgn0039213). It is a protein_coding_gene from Drosophila melanogaster. There is experimental evidence that it has the molecular function: guanyl ribonucleotide binding; protein homodimerization activity; GTPase activity. There is experimental evidence that it is involved in the biological process: membrane fusion; endoplasmic reticulum membrane fusion; regulation of microtubule depolymerization; neuromuscular junction development; regulation of synaptic growth at neuromuscular junction. 22 alleles are reported. The phenotypes of these alleles are annotated with: NMJ bouton; oocyte; postsynaptic membrane; dopaminergic neuron; abdominal 2 ventral longitudinal muscle 4; endoplasmic reticulum; embryonic/larval somatic muscle; abdominal 2 ventral longitudinal muscle 3. It has 2 annotated transcripts and 2 annotated polypeptides. Protein features are: Guanylate-binding protein, C-terminal; Guanylate-binding protein, N-terminal. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of high expression to a trough of moderately high expression. Peak expression observed within 00-18 hour embryonic stages, during late larval stages, during early pupal stages, in adult male stages. Summary of FlyAtlas Anatomical Expression Data: High or moderate levels of expression observed in all larval and adult organs/tissues. Expression at high levels in the following post-embryonic organs or tissues: adult head, adult eye, larval/adult central nervous system, adult crop, larval/adult midgut, larval/adult hindgut, larval/adult Malpighian tubules, adult heart, larval/adult fat body, larval/adult salivary gland, larval trachea, adult spermathecae, adult male accessory gland, larval/adult carcass. Expression at moderate levels in the following post-embryonic organs or tissues: adult brain, adult ovary, adult testis. Comments on Affy2 ProbeSet: ProbeSet 1638513_s_at completely aligns to an exonic region common to each of the 2 FlyBase-annotated transcript isoforms of atl. Gene sequence location is 3R:20451393..20460436.

In early oogenesis, atl protein is expressed in the posterior compartment of the egg chamber and in the membrane and cytoplasm of nurse cells. At oogenesis stage 9 it is found in the anterior cytoplasm of the oocyte. It then disapeears from this domain and at stage 10 atl protein is strongly expressed in follicle cells. In the adult brain it is expressed ubiquitously, with some cellls, including a subset of dopaminergic neurons expressing atl strongly.
atl is detected in neuropil regions of the brain and ventral nerve cord of third instar larvae. It is also detected in motor axon bundles emanating from the ventral ganglia. It is highly expressed throughout the cytolasm of body wall muscles and present at lower levels in the proximal parts of presynaptic arbors. It is not present in synaptic boutons.
Summary of FlyAtlas Anatomical Expression Data: High or moderate levels of expression observed in all larval and adult organs/tissues. Expression at high levels in the following post-embryonic organs or tissues: adult head, adult eye, larval/adult central nervous system, adult crop, larval/adult midgut, larval/adult hindgut, larval/adult Malpighian tubules, adult heart, larval/adult fat body, larval/adult salivary gland, larval trachea, adult spermathecae, adult male accessory gland, larval/adult carcass. Expression at moderate levels in the following post-embryonic organs or tissues: adult brain, adult ovary, adult testis.
