WebNational Center for Biotechnology Information WebFeb 19, 2014 · The protein components of the piRNA pathway localize to cytoplasmic nuage in the germ cells, such as intermitochondrial cement (IMC) and processing body (P-body). For instance, MILI, TDRD1 and DDX4 localize to IMC in pro-spermatogonia and pachytene spermatocytes, while MIWI2 and TDRD9 are components of the P-body [10] – …

By contrast to germline piRNA pathway, in Drosophila follicle cells, piRNA processing and maturation occurs at cytoplasmic perinculear “Yb body”.
WebAccordingly, nuage formation is thought to be RNA-independent. However, this notion is still controversial. UAP56, an export factor of piRNA precursors in germ cells, is localized to foci formed on dual-strand piRNA clusters. The nuclear foci are located near the cytoplasmic nuage, across the nuclear membrane .
