The gene α-Tubulin at 85E is referred to in FlyBase by the symbol Dmel\αTub85E (CG9476, FBgn0003886). It is a protein_coding_gene from Drosophila melanogaster. Based on sequence similarity, it is predicted to have molecular function: structural constituent of cytoskeleton. There is experimental evidence that it is involved in the biological process: mitotic spindle assembly checkpoint; cellular process; mitotic spindle organization; centrosome duplication. 6 alleles are reported. The phenotypes of these alleles are annotated with: spermatid; wing. It has one annotated transcript and one annotated polypeptide. Protein features are: Alpha tubulin; Tubulin; Tubulin, C-terminal; Tubulin, conserved site; Tubulin/FtsZ, 2-layer sandwich domain; Tubulin/FtsZ, C-terminal; Tubulin/FtsZ, GTPase domain. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of very high expression to a trough of very low expression. Peak expression observed within 12-24 hour embryonic stages, during early larval stages, during early pupal stages. Summary of FlyAtlas Anatomical Expression Data: Expression at high levels in the following post-embryonic organs or tissues: larval carcass. Expression at moderate levels in the following post-embryonic organs or tissues: adult testis. Comments on Affy2 ProbeSet: ProbeSet 1623910_at completely aligns to an exonic region of the only FlyBase-annotated transcript isoform of alphaTub85E. Gene sequence location is 3R:5556943..5558972.

To compare synthesis and accumulation of α-tubulin proteins, 35S</up>methionine radiolabeled tissues were subjected to Western analysis using monoclonal anti-α-tubulin antibody. Newly synthesized αTub85E protein was observed possibly in testes and imaginal disc tissue, but a stable pool was observed only in late embryos.

RNAi screen using dsRNA made from templates generated with primers directed against this gene in S2 cell results in dim staining of microtubules, and a short monopolar spindle. 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 causes a cell growth and viability phenotype when assayed in Kc167 and S2R+ cells.
In a sample of 79 genes with multiple introns, 33 showed significant heterogeneity in G+C content among introns of the same gene and significant positive correspondence between the intron and the third codon position G+C content within genes. These results are consistent with selection acting against preferred codons at the start of genes.
Though αTub84B and αTub85E are very similar in sequence they are functionally distinct. αTub85E can provide function in the male germ line fr generic microtubule arrays but lacks a subset of the functional properties possessed by necessary for specific features of microtubule assembly unique to the male germ cells.
The expression of βTub60D is accompanied by a coordinate transient increase in the level of synthesis of the embryonic α-tubulins, thereby maintaining an approximately equimolar synthesis of α- and β-tubulins throughout embryogenesis.
In D.melanogaster, two multigene families, each made up of four members, code for α- and β-tubulins. Tubulins are a highly conserved family of proteins that are the main structural components of microtubules in mitotic and meiotic spindles, cilia, flagella, neural processes and the cytoskeleton; nontubulin proteins (MAPS or microtubule-associated proteins) are involved along with tubulins in the formation of specialized microtubules (FBrf0045282; FBrf0046966). αTub85E is the only α-tubulin not expressed maternally. Transcripts present from 6-8 hr through adult. Protein found in support cells of chordotonal organs, developing muscles and somatic component of the testis (FBrf0049502). In adults expression of αTub85E is male-specific (FBrf0045282).
