The gene coracle is referred to in FlyBase by the symbol Dmel\cora (CG11949, FBgn0010434). It is a protein_coding_gene from Drosophila melanogaster. Based on sequence similarity, it is predicted to have molecular function: cytoskeletal protein binding. There is experimental evidence that it is involved in the biological process: adult somatic muscle development; embryonic morphogenesis; maintenance of imaginal disc-derived wing hair orientation; regulation of tube size, open tracheal system; establishment of glial blood-brain barrier. 44 alleles are reported. The phenotypes of these alleles are annotated with: organ system; organ system subdivision; external compound sense organ; adult; non-connected developing system; apical junction complex; adult segment; septate junction; dorsal trunk primordium; cell-cell junction; sense organ; embryonic foregut. It has 6 annotated transcripts and 6 annotated polypeptides. Protein features are: Band 4.1 domain; Band 4.1 family; Band 4.1, C-terminal; FERM adjacent (FA); FERM central domain; FERM conserved site; FERM domain; FERM, C-terminal PH-like domain; FERM, N-terminal; FERM/acyl-CoA-binding protein, 3-helical bundle; Pleckstrin homology-like domain. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of very high expression to a trough of low expression. Peak expression observed within 12-24 hour embryonic stages. Summary of FlyAtlas Anatomical Expression Data: Many larval and adult organs/tissues expressed at moderate or high levels. Expression at high levels in the following post-embryonic organs or tissues: larval/adult central nervous system, adult crop, larval trachea. Expression at moderate levels in the following post-embryonic organs or tissues: adult head, adult eye, larval/adult midgut, larval/adult hindgut, adult heart, larval/adult salivary gland, inseminated spermatheca, adult male accessory gland, larval/adult carcass. Comments on Affy2 ProbeSet: ProbeSet 1627454_a_at completely aligns to an exonic region common to each of the 4 FlyBase-annotated transcript isoforms of cora. Gene sequence location is 2R:15116568..15131256.

Antibodies were prepared against sequences from
the 5' end of the coding sequence that are shared by all of the cora
cDNAs as well as to a region specific to the 1698aa species. The staining
pattern obtained with both antisera are not noticably different.
The 6.3kb cora transcript is first detected in 4-8hr embryos, is much more abundant in 8-12hr embyros and remains prevalent through embryonic and larval stages.
cora protein appears to be associated with the cytoplasmic face of septate junctions in epithelial cells. It does not appear to co-localize to a great extent with either filamentous actin or spectrin in the apical-basal axis of the cell.
cora protein is first observed at the onset of germ band retraction in the epidermis, the hindgut, and the foregut. As the germ band retracts, expression increases in these tissues and appears in the tracheal branches and in the salivary glands. It is not expressed in the CNS but is observed in some sensory neural cells such as the scolopidia of the pentascolopidial chordotonal organ.
Summary of FlyAtlas Anatomical Expression Data: Many larval and adult organs/tissues expressed at moderate or high levels. Expression at high levels in the following post-embryonic organs or tissues: larval/adult central nervous system, adult crop, larval trachea. Expression at moderate levels in the following post-embryonic organs or tissues: adult head, adult eye, larval/adult midgut, larval/adult hindgut, adult heart, larval/adult salivary gland, inseminated spermatheca, adult male accessory gland, larval/adult carcass.

The amino-terminal 383 amino acids of cora define a functional domain that is both necessary and sufficient for proper septate junction localisation of the protein. This domain and the cytoplasmic domain of Nrx-IV interact directly.
Some of the proteins of apico-lateral junctions are required both for apico-basal cell polarity and for the signalling mechanisms controlling cell proliferation, whereas others are required more specifically in cell-cell signalling.
