In Drosophila, miRNA strands are predominantly sorted into AGO1 to regulate seed-matched target transcripts, while their partner miRNA* strands are thought to be mostly degraded. Here, we report that Drosophila Argonautes exhibit different strand preferences for miRNA duplexes, and that in particular, many miRNA* species accumulate in the RNAi effector AGO2. AGO2-loaded miRNA* species require canonical RNAi factors for their accumulation, are efficiently 3' modified, and are preferentially activ ...[more]
