The study identifies the human AGO–HSP90–p23 complex, known as the AGO maturation complex (AMC), which captures AGO in an RNA-free state and facilitates RNA loading and AGO folding, thus elucidating the mechanism of RNA-induced silencing complex (RISC) assembly. The findings reveal how chaperones and RNA duplexes guide the folding of AGO, providing insights for the rational design of small interfering RNA therapeutics.
The study provides a significant insight into RNA-induced silencing complex (RISC) assembly by revealing the structure and function of the AGO maturation complex (AMC), which includes human AGO, HSP90, and p23. This discovery not only elucidates how small RNA duplexes facilitate AGO folding and RISC assembly but also establishes AMC as a potential tool for designing small interfering RNA therapeutics, highlighting a promising direction for future biomedical applications.
