abstract：:Nuclear cap-binding protein (CBP) 80/20-dependent translation (CT) is one of the targets for miRNA-mediated gene silencing. Here, we provide evidence that human argonaute 2 (Ago2) competes with CBP80/20 for cap-association, inhibiting CT and thus nonsense-mediated mRNA decay (NMD), which is tightly coupled to CT. Teth...
