For each annotated gene, all transcripts are shown with the complete intron/exon structure (exon (wider bars) and intron (black line)). Coding regions are shown in blue and untranslated regions are uncolored. The gene region is hyperlinked to a pop-up window containing an automated gene summary and links to the FlyBase Gene Report and NCBI gene report; labels shows FlyBase transcript symbols.

See Computed cytological data in FlyBase for a detailed description of how this computed cytological location is calculated. See FlyBase Maps for a collection of polytene chromosome images.

Nucleotide view When zoomed in, the DNA sequence of the Release 6 (R6) (Hoskins et al, 2015) genome is shown. The bases are color-coded, G-yellow, A-green, T-red, C-blue. When zoomed in (150 bp or less) the bases are colored and labeled (GATC). Between 150 and 750 bp, the bases are colored but not labeled. Above and below the base representation, the three-frame translation for the plus and minus strands is shown using the single-letter amino acid code. Start codons (M and L) are indicated in green and stop codons are marked in red.

Mapped Mutations

Transgenic insertion site SO:0000368 Indicated by vertical bars with an arrow indicating orientation if known. An insertion indicated with an arrow pointing to the right is oriented with its conventional 5' terminus to the left (assuming view is in conventional orientation of the Drosophila chromosome); this is described as being in the "plus" orientation. An insertion indicated with an arrow pointing to the left is oriented with its conventional 5' terminus to the right (assuming view is in conventional orientation of the Drosophila chromosome); this is described as being in the "minus" orientation. An insertion with no arrow has an unknown orientation. For all insertions, if the estimated insertion site is larger than 10 nucleotides, the insertion is shown as a blue box rather than a vertical line. In those cases, see the Insertion Report for more information about localization. Insertions are linked to their respective Insertion Report.

The location of the mutation is indicated with a red box and labeled with the FlyBase Allele symbol. The feature glyph is linked to the related Allele Report.

Uncharacterized change in nucleotide sequence SO:1000007 The nature of the nucleotide substitution is either uncharacterized or only partially characterized.

Location of mutation is indicated with a red bar and labeled with the FlyBase allele symbol. Feature is linked to the related Allele Report.

Indel SO:1000032 The junction where an insertion or deletion of one or more nucleotides occurred. Location of mutation is indicated and labeled with the FlyBase allele symbol. In the case of deletions, the extent of the deletion is indicated by a red bar. In the case of nucleotide insertions, the location of the nucleotide(s) insertion is indicated by a vertical line. Features are linked to the related Allele Report.

Rescue fragment SO:0000411 Locations of transgenic rescue fragment reported in the literature. Labeled with FlyBase allele symbol designation. Features are linked to the related Allele Reports which contain genetic data.
