Important message

Updated sequence information for this Drosophila species is no longer provided by FlyBase. Gene model annotations for this species are now updated and maintained at NCBI, using the gnomon automated annotation pipeline. See the NCBI page ‘Eukaryotic genomes annotated at NCBI’.

The FlyBase BLAST tool will continue to support queries against the reference genome of this species, but not queries against annotated transcripts or proteins. For the current release, there is no JBrowse or GBrowse view of the gene model annotations for this species.

The FlyBase archived release FB2017_05 includes the last NCBI annotation update for this species that was imported into FlyBase. That sequence data can be accessed from archived gene reports, via the archived GBrowse tool, and via archived bulk-data downloads.

                    Polypeptides from B-H1 of D.melanogaster and Dana\B-H1 of D.ananassae have homeodomains identical in sequence except for one amino acid replacement: the conserved Phe in helix 3 is replaced by Tyr.

                    (Kojima et al., 1991)

                    May be homologous to the Bar gene of D.melanogaster.

                    (Hinton, 1984)

                    Considerable quantitative variation between the 11 mutants. Eye tissue reductions accompanied by more or less prominent anterior indentation and by jumbled ommatidia around the indentations; orthogonal arrays of ommatidia seen beyond the indentation.
