Yb Integrates piRNA Intermediates and Processing Factors into Perinuclear Bodies to Enhance piRISC Assembly
PIWI-interacting RNAs (piRNAs) direct Piwi to repress transposons and maintain genome integrity in Drosophila ovarian somatic cells.piRNA maturation and association with Piwi occur at perinuclear Yb bodies, the centers of piRNA biogenesis.Here, we show that piRNA intermediates arising from the piRNA cluster norway maple crimson sentry flamenco (fla
