Webtarget mRNA and RISC components have been co-localized in P-bodies [29,31], it is possible that P-bodies are the bona fide site for RISC-induced target cleavage or repression of trans-lation. However, the mechanism by which target mRNA and miRISC are directed to P-bodies and how translation is repressed by miRISC is still unknown. WebThe microRNA RNP complex is called the RNA-induced silencing complex (RISC), and similar to snRNPs, the RISC uses a small RNA (microRNA) to direct sequence-specific recruitment of the RISC to its target RNA. ...
