Tudor domain containing protein 5-like(Tdrd5l) identifies a novel germline body and regulates maternal RNAs during oogenesis

In this study we show that Drosophila Tudor-domain containing protein 5-like (Tdrd5l) is important for post-transcriptional regulation of maternal mRNAs. Tdrd5l localizes to a novel of body in the germline and interacts with post-transcriptional regulation pathways. In mutant females we observe accumulation of Gurken and its activator Orb in nurse cells during oogenesis. Decreased orb function suppresses the Tdrd5l-mutant phenotype, indicating that this is a primary defect in these mutants. Gene expression comparison between Tdrd5l mutant testes and control testes. Additional gene expression analysis between Tdrd5l mutant ovaries and control ovaries
