WebAug 19, 2024 · In germline cells, piRNA processing occurs at cytoplasmic perinuclear, multi-protein structures “nuage” where mature piRNAs are produced and are loaded onto PIWI proteins; Aub, Ago3. By contrast to germline piRNA pathway, in Drosophila follicle cells, piRNA processing and maturation occurs at cytoplasmic perinculear “Yb body”. WebDue to the lack of TSKS-derived nuage (TDN), the cytoplasmic contents cannot be eliminated from spermatid cytoplasm in Tsks knockout mice, resulting in excess residual cytoplasm with an abundance of cytoplasmic materials and inducing an apoptotic response.
