The gene Deoxyribonuclease II is referred to in FlyBase by the symbol Dmel\DNaseII (CG7780, FBgn0000477). It is a protein_coding_gene from Drosophila melanogaster. Based on sequence similarity, it is predicted to have molecular function: deoxyribonuclease II activity. There is experimental evidence that it is involved in the biological process: nurse cell apoptotic process. 11 alleles are reported. The phenotype of these alleles is annotated with: ovary. It has one annotated transcript and one annotated polypeptide. Protein features are: Deoxyribonuclease II. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of high expression to a trough of low expression. Peak expression observed within 00-12 and 18-24 hour embryonic stages, at stages throughout the larval period, at stages throughout the pupal period. Summary of FlyAtlas Anatomical Expression Data: Expression at high levels in the following post-embryonic organs or tissues: adult head, adult heart, larval/adult fat body, adult salivary gland, adult spermathecae, adult carcass. Expression at moderate levels in the following post-embryonic organs or tissues: adult eye, adult central nervous system, larval/adult hindgut. Comments on Affy2 ProbeSet: ProbeSet 1640898_at completely aligns to an exonic region of the only FlyBase-annotated transcript isoform of DNaseII. Gene sequence location is 3R:13845097..13846883.

DNase-1: Deoxyribonuclease-1
The structural gene for DNase 1, one of an estimated
7 or more DNase species (Boyd, 1964, Biophys. Biochem. Acta
171: 103-12). Active on native DNA at acid pH
(optimum = 4.8) and in the presence of EDTA. Heterozygotes
for electrophoretic alleles show two bands on gels indicating
monomeric nature of enzyme. Activity of paternally inherited
allele demonstrable in 0- to 1-hr embryos. Activity fluctuates during embryogenesis, is low during larval stages, rises
precipitously just before pupation, and falls after eclosion
(Detwiler and MacIntyre, 1978). DNase-1 activity isolated
with lysosomal fraction of embryo homogenates (Detwiler and
MacIntyre, 1980, Insect Biochem. 10: 255-63). Flies homozygous for hypomorphic allele are small with reduced viability;
maturation of ovaries delayed for several days after eclosion;
recombination normal (Grell, 1976). Homozygotes for the hypomorphic allele DNase1lmn accumulate low-molecular-weight,
low-thermal-stability DNA, especially in the ovaries;
Feulgen-positive vesicles visible in maturing oocytes near
chorionic appendages (Stone, Dower, Hauseman, Cseko and Sederoff, 1983, Can. J. Genet. Cytol. 25: 129-38).
