Project description:Identification and annotation of all the genes in the sequenced Drosophila genome is a work in progress. Wild-type testis function requires many genes and is thus of potentially high value for the identification of transcription units. We therefore undertook a survey of the repertoire of genes expressed in the Drosophila testis by computational and microarray analysis. We generated 3141 high-quality testis expressed sequence tags (ESTs). Testis ESTs computationally collapsed into 1560 cDNA set used for further analysis. Of those, 11% correspond to named genes, and 33% provide biological evidence for a predicted gene. A surprising 47% fail to align with existing ESTs and 16% with predicted genes in the current genome release. EST frequency and microarray expression profiles indicate that the testis mRNA population is highly complex and shows an extended range of transcript abundance. Furthermore, >80% of the genes expressed in the testis showed onefold overexpression relative to ovaries, or gonadectomized flies. Additionally, >3% showed more than threefold overexpression at p <0.05. Surprisingly, 22% of the genes most highly overexpressed in testis match Drosophila genomic sequence, but not predicted genes. These data strongly support the idea that sequencing additional cDNA libraries from defined tissues, such as testis, will be important tools for refined annotation of the Drosophila genome. Additionally, these data suggest that the number of genes in Drosophila will significantly exceed the conservative estimate of 13,601. Keywords: other

Project description:Post-transcriptional gene regulatory mechanisms are fundamental to the determination of gene expression dynamics and especially crucial for the earliest stages of animal development in which transcription is nearly silent. Here we performed high-resolution total RNA-sequencing and quantitative mass spectrometry analysis simultaneously on Drosophila maternal-to-zygotic transition (MZT) to reveal the dynamic interchange between transcript and protein expression level at the earliest stage of animal development. Intriguingly, we found that both stable transcript expression and an increase in translation efficiency can be crucial for protein upregulation prior to zygotic gene activation (ZGA), whereas such features diminished following ZGA. Further, this study is the first to report the proteome-wide quantitative changes in protein ubiquitination in Drosophila MZT. Our results indicate that timely ubiquitination of the distinct target proteins during MZT are essential for the downregulation of protein expression levels. Profiling of the RNA-associated proteome changes in Drosophila MZT suggested that RNA-binding activities can be regulated without the respective change in net protein expression levels for over 200 proteins, including Pcid2, Sym, and Cpsf73. Taken together, we find that stable expression of transcript can be crucial for the protein expression level upregulation during the earliest stage of MZT, and also report that proteome wide and quantitative remodeling of the distinct post translational regulatory mechanisms can be crucial for the gene expression level changes and progression of the earliest stages of animal development.
