pubmed:abstractText |
Here we show that RNA interference (RNAi) machinery operates in Drosophila melanogaster 1.688 satellite transcription. Mutation in the spn-E gene, known to be involved in RNAi in the oocytes, causes an increase of satellite transcript abundance. Transcripts of both strands of 1.688 satellite repeats in germinal tissues were detected. The strength of the effects of the spn-E mutation differs for 1.688 satellite DNA subfamilies and is more pronounced for autosomal pericentromeric satellites compared to the X-linked centromeric ones. The spn-E(1) mutation causes an increase of the H3-AcK9 mark and TAF1 (a component of the polymerase II transcriptional complex) occupancy in the chromatin of autosomal pericentromeric repeats. Thus, we revealed that RNAi operates in ovaries to maintain the silenced state of centromeric and pericentromeric 1.688 repeats.
