The 26S proteasome consists of a 20S proteasome core and two 19S regulatory subunits. The 20S proteasome core is composed of 28 subunits that are arranged in four stacked rings, resulting in a barrel-shaped structure. The two end rings are each formed by seven alpha subunits, and the two central rings are each formed by seven beta subunits. The catalytic chamber with the active sites is on the inside of the barrel (By similarity).

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.
For each fully sequenced cDNA the DGRC maintains various forms of the cDNA (e.g tagged or untagged) in several different host vectors for subsequent cloning and expression in Drosophila and Drosophila cell lines.

The nomenclature of genes encoding subunits of the 26S proteasome of D. melanogaster have been standardized according to FBrf0215459. These symbols/names largely follow those used already in FlyBase, and largely mirror fly community usage. HOWEVER, note that at least one other nomenclature system exists that is followed by the HUGO Gene Nomenclature Committee (HGNC), for example, with the unfortunate result that several D. melanogaster genes have shared synonyms.

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 generated by PCR using primers directed to this gene causes a cell growth and viability phenotype when assayed in Kc167 and S2R+ cells.
