WebFeb 28, 2011 · Nuage (or commonly known as chromatoid body in mammals) is a conserved germline-specific organelle that has been linked to the Piwi-interacting RNA (piRNA) pathway. piRNAs are a class of gonadal-specific RNAs that are ~23-29 nucleotides in length and protect genome stability by repressing the expression of deleterious … WebSuch long precursor transcripts have to be exported to cytoplasmic perinuclear granules called nuage, where the biogenesis factors reside. In Drosophila, two distinct piRNA biogenesis pathways are operational in the two ovarian compartments (somatic follicle cells and the germline).
