With the rapid proliferation of RNAi applications in basic and clinical sciences, the challenge has now become understanding how components of RNAi machinery function together in a regulated manner. Argonaute proteins are the central effectors of RNAi and are highly conserved among eukaryotes and some archaebacteria. These RNA-binding proteins use small guide RNAs to silence expression of genes at the mRNA and DNA levels. InArgonaute Proteins: Methods and Protocols, expert researchers in this burgeoning field provide detailed, up-to-date methods to study Argonaute protein functions...
