| Outline of Final Research Achievements |
RNA silencing, such as RNA interference and gene silencing by microRNAs, is a gene regulation system universally conserved in eukaryotes. The RNA-induced silencing complex, which is composed of an Argonaute protein and a single-stranded RNA, plays a central role in this system. However, the detailed mechanisms of RISC assembly remained elusive. In this project, by single-molecule imaging approach using total-internal reflection microscopy, I have tried to visualize how RISC is assembled, and revealed the fundamental steps in RISC assembly.
