Translation and codon usage regulate Argonaute slicer activity to trigger small RNA biogenesis
Abstract
22G-RNAs are single-stranded antisense small RNAs that are expressed in C. elegans germline. Here the authors show that CSR-1 dependent 22G-RNAs are produced in the cytosol on mRNAs actively engaged in translation and that codon usage of an mRNA regulates the biogenesis of CSR-1 dependent 22G-RNAs.
