The gene Proteasome β7 subunit is referred to in FlyBase by the symbol Dmel\Prosβ7 (CG12000, FBgn0250746). It is a protein_coding_gene from Drosophila melanogaster. Based on sequence similarity, it is predicted to have molecular function: endopeptidase activity. There is experimental evidence that it is involved in the biological process: centrosome organization; mitotic spindle elongation; cell proliferation; cellular process; response to DNA damage stimulus; mitotic spindle organization; neurogenesis. 7 alleles are reported. No phenotypic data is available. It has 2 annotated transcripts and 2 annotated polypeptides. Protein features are: Proteasome B-type subunit; Proteasome endopeptidase complex, beta subunit; Proteasome, beta-type subunit, conserved site; Proteasome, subunit alpha/beta. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of very high expression to a trough of high expression. Peak expression observed within 00-12 hour embryonic stages, at stages throughout the larval period, at stages throughout the pupal period, in stages of adults of both sexes. 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: adult head, adult eye, larval central nervous system, adult crop, larval/adult midgut, larval/adult hindgut, larval/adult Malpighian tubules, adult heart, larval/adult fat body, larval/adult salivary gland, larval trachea, adult female reproductive system, adult male reproductive system, larval/adult carcass. Expression at moderate levels in the following post-embryonic organs or tissues: adult central nervous system. Comments on Affy2 ProbeSet: ProbeSet 1630851_s_at completely aligns to an exonic region common to each of the 2 FlyBase-annotated transcript isoforms of Prosbeta7. Gene sequence location is 3R:1182734..1184086.

cDNA Clones ( 114 )
Please Note
This section lists
cDNAs and ESTs that fall within the genomic extent
of the gene model, which may include cDNAs and ESTs
of genes within introns, or of overlapping genes.
Please see GBrowse for alignment of the cDNAs and ESTs
to the gene model.
FlyBase curator comment: the symbol "Prosβ4" has been used to describe two different genes in the literature; it is used to refer to the gene corresponding to the CG17331 annotation in FBrf0152082, while it is used refer to the gene corresponding to the CG12000 annotation in FBrf0200397 and FBrf0201458. To try and minimise confusion, "Prosβ4" is not used as the valid symbol for either gene in FlyBase, but the "Prosβ4" synonym present under both genes.
RNAi screen using dsRNA made from templates generated with primers directed against this gene results in the formation of short, monastral spindles and severe proliferation defects when assayed in S2 cells. This phenotype can be observed when the screen is performed with or without Cdc27 dsRNA.
RNAi screen using dsRNA made from templates generated with primers directed against this gene in S2 cells does not affect the number of prophase centrosomes, but monastral bipolar spindles are formed during mitosis, suggesting that the centrosomes are fused.
RNAi screen using dsRNA made from templates generated with primers directed against this gene causes a cell growth and viability phenotype when assayed in Kc167 and S2R+ cells.
Area matching Drosophila EST AA441362. This EST has sequence similarity to mammalian proteasome subunit HsN3. Probable intron in gene represented by EST AA441362.
