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.

Gene Summary
Molecular chaperone that promotes the maturation, structural maintenance and proper regulation of specific target proteins involved for instance in cell cycle control and signal transduction. Undergoes a functional cycle that is linked to its ATPase activity. This cycle probably induces conformational changes in the client proteins, thereby causing their activation. Interacts dynamically with various co-chaperones that modulate its substrate recognition, ATPase cycle and chaperone function. Required for piRNA biogenesis by facilitating loading of piRNAs into PIWI proteins (By similarity). (UniProt, P04809)

                    A dendrogram of protein sequence for representative members of the HSP90 family is generated.

                    The frequency distribution of "silent" DNA polymorphisms has been studied in a number of D.simulans and D.pseudoobscura.pseudoobscura genes.

                    Insertions of Tn\neoR22.Dpse\Hsp83 at euchromatic sites on the X chromosome of D.melanogaster are fully dosage compensated in both adults and larvae. Autosomal insertions and an insertion in a β-heterochromatic region of the X chromosome are not compensated at either stage. Heat induced activity of Tn\neoR22.Dpse\Hsp83 at insertion sites demonstrates an absence of position effect.

                    The Dpse\Hsp83 promoter directs similar levels of reporter gene expression in D.melanogaster and L.cuprina embryos, indicating that this promoter can function efficiently in the non-drosophilid L.cuprina.

                    Chromosome homologies of Muller's element D (J chromosome in the Paleartic species and XR chromosome arm in Nearctic species) and of element E (O chromosome in the Paleartic species and 2 chromosome in Nearctic species) have been confirmed by single copy probes in the species of the obscura group and in D.melanogaster.

                    Dpse\Hsp83 promoter is more active in a wider range of insect species than the more commonly used Hsp70A, Hsp70B or Act5C.

                    Transcribed larval mRNA was measured from the autosomal Adh gene and the X chromosomal Dpse\Hsp83 gene, both carried on the same P-element construct. Both genes are fully dosage compensated at transposon insertion sites in the euchromatic regions of the X chromosome but neither were compensated at an insertion site in the β-heterochromatin of the X chromosome. No compensation of the Dpse\Hsp83 gene was found at any of the autosomal insertion sites. The compensation behaviour of the transposed genes was determined by their new chromosomal environment.

                    Sequence analysis of the Hsp83 gene in several species reveals a conserved 5' 34 base pair imperfect dyad made up of three overlapping copies of the consensus heat shock regulatory sequence. The region from -21 to -133 is repeated further upstream, possibly related to dosage compensation.
