WebThe pre-miRNA stem-loop is cleaved by Dicer into two complementary short RNA molecules, but only one is integrated into the RISC complex. This strand is known as the guide strand and is selected by the argonaute protein. The remaining strand, known as the anti-guide or passenger strand, is degraded as a RISC complex substrate. WebMar 8, 2013 · MicroRNAs (miRNAs) are 22-nt noncoding RNAs that regulate gene expression by associating with the multiprotein RNA-induced silencing complex (RISC) and guiding RISC to silence specific mRNA …

The Argonaute protein family, first discovered for its evolutionarily conserved stem cell function, plays a central role in RNA silencing processes as essential components of the RNA-induced silencing complex (RISC). RISC is responsible for the gene silencing phenomenon known as RNA interference (RNAi). Argonaute proteins bind different classes of small non-coding RNAs, including
