Happy to see our study out! We define the sequence determinants for miRNA-target interactions in flies and provide a foundation for improving computational prediction of miRNA-mediated regulation in Drosophila.

Biochemical principles of miRNA targeting in flies - Nature Communications
MicroRNAs guide Argonaute proteins to repress gene expression. Here, the authors define the binding rules for five Drosophila miRNAs, showing a narrow preference for canonical seed sites and identifyi...

Hot off the press from the Zamore & Gainetdinov labs: Cleavage of mRNAs by a minority of pachytene piRNAs improves sperm fitness 🏊️ buff.ly/O40kIi3 #piRNA #mRNA #fertility
Cleavage of mRNAs by a minority of pachytene piRNAs improves sperm fitness - Nature
Most pachytene PIWI-interacting RNAs (piRNAs) have no biological function; however, a small population enhances sperm fitness, which has led to their persistence in mammalian evolution.
