The gene Diuretic hormone 44 is referred to in FlyBase by the symbol Dmel\Dh44 (CG8348, FBgn0012344). It is a protein_coding_gene from Drosophila melanogaster. Based on sequence similarity, it is predicted to have molecular function: neuropeptide hormone activity. There is experimental evidence that it is involved in the biological process: body fluid secretion. 5 alleles are reported. No phenotypic data is available. It has 2 annotated transcripts and 2 annotated polypeptides. Protein features are: Corticotropin-releasing factor conserved site; Corticotropin-releasing factor, CRF. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of moderate expression to a trough of no expression detected. Peak expression observed within 18-24 hour embryonic stages, during early larval stages, in adult male stages. Summary of FlyAtlas Anatomical Expression Data: Expression at high levels in the following post-embryonic organs or tissues: adult brain. Expression at moderate levels in the following post-embryonic organs or tissues: adult head, larval/adult central nervous system. Comments on Affy2 ProbeSet: ProbeSet 1634957_at completely aligns to an exonic region common to each of the 2 FlyBase-annotated transcript isoforms of Dh. Gene sequence location is 3R:5463904..5476428.

This section lists
cDNAs and ESTs that fall within the genomic extent

FlyBase Curator comment: 'Dh' (FBgn0012344) renamed to 'Dh44' to reflect usage in the literature, to clearly distinguish it from 'Dh31' (FBgn0032048) and 'dh' (FBgn0014147), and for consistency with the nomenclature of 'Dh44-R1' (FBgn0033932) and the other diuretic hormone and diuretic hormone receptor genes.
