Abstract: Abstract: RNA silencing is a conserved gene regulation mechanism with specificity determined by small RNAs of ~21 nt. RNA silencing underlies many fundamental biological processes and has become an important technique for research and therapeutic application. Structural studies of RNA silencing components have revealed molecular details in the processing, transportation, modification and functioning of small RNAs and many unique protein-RNA recognition modes.
Key words: RNA interference; three-dimensional structure; RNase III; Argonaute; RNA transport;RNA methylation
