Export of piRNA precursors by EJC triggers assembly of cytoplasmic Yb-body in Drosophila

Abstract

In Drosophila ovarian follicle cells, piRNAs generated from RNA precursors are processed in cytoplasmic Yb-bodies. The authors identify the exportin and the exon junction complexes as required to transfer precursors to cytoplasm. They also show that Yb-body formation requires piRNA precursor export.
