The gene hyperplastic discs is referred to in FlyBase by the symbol Dmel\hyd (CG9484, FBgn0002431). It is a protein_coding_gene from Drosophila melanogaster. Based on sequence similarity, it is predicted to have molecular function: ubiquitin-protein ligase activity. There is experimental evidence that it is involved in the biological process: male meiosis cytokinesis; spermatid nucleus differentiation; female gonad development; imaginal disc development; eye-antennal disc morphogenesis; imaginal disc growth; spermatogenesis. 44 alleles are reported. The phenotypes of these alleles are annotated with: organ system; multicellular structure; anatomical structure; organelle; imaginal precursor; thoracic segment; embryonic/larval imaginal precursor; intracellular organelle part; centrosome; organ system subdivision; elongation stage spermatid; nucleus. It has 2 annotated transcripts and 2 annotated polypeptides. Protein features are: E3 ubiquitin ligase EDD, ubiquitin-associated domain; HECT; Polyadenylate-binding protein/Hyperplastic disc protein; Regulator of chromosome condensation 1/beta-lactamase-inhibitor protein II; Ubiquitin-associated/translation elongation factor EF1B, N-terminal, eukaryote; Zinc finger, N-recognin; Zinc finger, N-recognin, metazoa. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of high expression to a trough of moderate expression. Peak expression observed within 00-06 hour embryonic stages. Summary of FlyAtlas Anatomical Expression Data: High or moderate levels of expression observed in all larval and adult organs/tissues. Expression at high levels in the following post-embryonic organs or tissues: larval central nervous system, adult crop, adult Malpighian tubules, larval/adult salivary gland, larval trachea, adult ovary, adult testis. Expression at moderate levels in the following post-embryonic organs or tissues: adult head, adult eye, adult central nervous system, larval/adult midgut, larval/adult hindgut, larval Malpighian tubules, adult heart, larval/adult fat body, adult spermathecae, adult male accessory gland, larval/adult carcass. Comments on Affy2 ProbeSet: ProbeSet 1641297_at completely aligns to an exonic region of the only FlyBase-annotated transcript isoform of hyd. Gene sequence location is 3R:5540345..5551337.

l(3)85Ea
l(3)85Ea1 is a heat-sensitive allele. At 20 about
half the expected number of homozygotes eclose, the remainder
dying as pharate adults; those that emerge are sterile,
ovaries failing to mature, testes appearing morphologically
normal; they also exhibit other slight abnormalities such as
extra sex-comb teeth and defective wing margins. At 22 all
flies die as pharate adults with greatly reduced heads, often
with duplicated antennal and palpal structures. No metamorphosis accompanies development at 25; the eye disc is virtually missing, whereas the wing and haltere discs are severely
hyperplastic; disc effects autonomous in transplants.
Temperature-shift experiments demonstrate a temperature-sensitive period lasting from the beginning of the second
instar until the end of pupation. The 24-hr pulses of 27 during development reveal that the various phenotypic consequences of homozygosity for this allele have different TSP's.
l(3)85Ea1 wing discs used to demonstrate that extra cellular
proliferation is insufficient to induce transdetermination
(Shearn, Martin, Davis, and Hersperger, 1984, Dev. Biol.
106: 135-46). Density of gap junctions in hyperplastic imaginal wing discs markedly reduced (Ryerse and Nagel, 1984,
Dev. Biol. 105: 396-403); in shift-up experiments, reduction in gap junctions precedes the onset of tissue hyperplasia
(Ryerse and Nagel, 1985, Wilhelm Roux's Arch. Dev. Biol.
194: 480-86). Cell death also observed in wing discs as
early as twelve hours following application of restrictive
temperature (Sedlak, 1986, Dev. Genet 6: 199-212). Mitosis
normal (Gatti and Baker, 1989, Genes Dev. 3: 438-53).

Cells in the eye disc that are mutant for hyd ectopically express dpp and hh in anterior regions of the disc, leading to premature photoreceptor differentiation and overgrowth of surrounding tissue.
Endocrine mechanisms responsible for the prolongation of larval life in hyd mutants were investigated: results suggest that delayed pupariation is caused by the overgrown imaginal discs inhibiting the production or release of ecdysteroids from the endocrine system.
