The gene Gliotactin is referred to in FlyBase by the symbol Dmel\Gli (CG3903, FBgn0001987). It is a protein_coding_gene from Drosophila melanogaster. Based on sequence similarity, it is predicted to have molecular function: carboxylesterase activity. There is experimental evidence that it is involved in the biological process: synaptic target recognition; female meiosis chromosome segregation; maintenance of imaginal disc-derived wing hair orientation; border follicle cell migration; establishment of blood-nerve barrier; regulation of tube size, open tracheal system; septate junction assembly. 47 alleles are reported. The phenotypes of these alleles are annotated with: organ system subdivision; organ system; peripheral nervous system; adult segment; thoracic segment; eo support cell; apical junction complex; multicellular structure; sense organ; septate junction. It has 5 annotated transcripts and 5 annotated polypeptides. Protein features are: Carboxylesterase type B, conserved site; Carboxylesterase, type B. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of high expression to a trough of low expression. Peak expression observed within 06-12 hour embryonic stages. Summary of FlyAtlas Anatomical Expression Data: Expression at high levels in the following post-embryonic organs or tissues: larval trachea. Expression at moderate levels in the following post-embryonic organs or tissues: adult head, adult eye, larval central nervous system, adult crop, larval/adult hindgut, larval/adult salivary gland, adult spermathecae, adult male accessory gland, larval/adult carcass. Comments on Affy2 ProbeSet: ProbeSet 1624203_s_at completely aligns to an exonic region common to each of the 5 FlyBase-annotated transcript isoforms of Gli. Gene sequence location is 2L:15756001..15762755.

Gli transcripts are expressed in most peripheral glia, in some exit glia, and in a number of midline glia. Prior to glial staining, there is some epidermal staining in broad, diffuse stripes at early stage 12.
Gli protein is expressed in most peripheral glia, in some exit glia, and in a number of midline glia. Staining of peripheral glia is first detected at stage 13 and becomes stronger through later stages. At stages 16-17, the entire surface of these glia appears to stain. The Gli-expressing glia extend from the nerve roots just inside the CNS along most of the major peripheral nerves, including the ISN up to the main tracheal trunk and along the two SN branches. Gli protein is expressed on all glia associated with the peripheral motor and sensory nerves but is not expressed on glia associated with sensory structures. Gli protein is also observed in a pair of midline glial cells at stages 16 and 17, in the epidermis from stage 12, and in the trachea and hindgut. In larvae, faint staining is observe in the midline of the thoracic ganglia, along the large nerve trunks leaving the CNS, in leg and antennal discs, in trachea and in the PNS.
Summary of FlyAtlas Anatomical Expression Data: Expression at high levels in the following post-embryonic organs or tissues: larval trachea. Expression at moderate levels in the following post-embryonic organs or tissues: adult head, adult eye, larval central nervous system, adult crop, larval/adult hindgut, larval/adult salivary gland, adult spermathecae, adult male accessory gland, larval/adult carcass.

of genes within introns, or of overlapping genes.
Please see GBrowse for alignment of the cDNAs and ESTs
to the gene model.
FlyBase curator comment: "EP2416" overexpression phenotype stated to be due to its effect on Gli but orientation of the P{EP} element suggests otherwise.
In mutant embryos peripheral glia develop normally in terms of migration and differentiation except that ultrastructurally and physiologically they do not form a complete blood-nerve barrier. As a result peripheral motor axons are exposed to high K+ haemolymph, action potentials fails to propagate and the embryos are nearly paralysed.
