[https://www.uniprot.org/uniprot/MAEL_DROME MAEL_DROME] Involved both in the piRNA and miRNA metabolic processes. As a component of the meiotic nuage, plays a central role during oogenesis by repressing transposable elements and preventing their mobilization, which is essential for the germline integrity. Repression of transposable elements is mediated via the piRNA metabolic process, which mediates the repression of transposable elements during meiosis by forming complexes composed of piRNAs and Piwi proteins and governs the repression of transposons. As a nuclear component, it is required for proper differentiation in the germline stem cell (GSC) lineage by repressing microRNA-7 (miR-7), thereby acting as an indirect regulator of bag-of-marbles (Bam). Acts by binding to the promoter of miR-7 gene and repressing its expression; miR-7 repression alleviates the Bam repression by miR-7, thereby allowing differentiation in the germline stem cell (GSC) lineage. Indirectly required to position the microtubule organizing center in stage 2-6 oocytes.<ref>PMID:11277405</ref> <ref>PMID:12538514</ref> <ref>PMID:17428915</ref> <ref>PMID:19758565</ref> <ref>PMID:23159368</ref>
