Pros29, α3, Proteasome 29kD subunit
Gene model reviewed during 5.45
There is only one protein coding transcript and one polypeptide associated with this gene
264 (aa); 29 (kD predicted)
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). Interacts with PI31.

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.
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.
