Post-transcriptional control of mRNAs by RNA-binding proteins (RBPs) has a prominent role in the regulation of gene expression. RBPs interact with mRNAs to control their biogenesis, splicing, transport, localization, translation, and stability. Defects in such regulation can lead to a wide range of ...
Organisms exhibit a fascinating array of gene-silencing pathways, which have evolved in part, to confront invasive nucleic acids such as transposons and viruses. A key question raised by the existence of these pathways is how do they distinguish M-bM-^@M-^\selfM-bM-^@M-^] from M-bM-^@M-^\non-selfM-b...
Argonaute proteins (AGOs) are key nuclease effectors of RNA interference (RNAi) [1]. Although purified AGOs can mediate a single round of target-RNA cleavage in vitro, accessory factors are required for siRNA loading and to achieve multiple-target turnover [2, 3]. To identify AGO co-factors we immun...

Diverse naturally-occurring small RNA species interact with Argonaute proteins to mediate sequence-specific regulation in animals. In addition to micro-RNAs (miRNAs), which collectively regulate thousands of target mRNAs, other endogenous small RNA species include the Piwi-associated piRNAs that are...
