Structural Insights Into the Human Gw182-Pabc Interaction in Microrna-Mediated Deadenylation
Nat.Struct.Mol.Biol., 17:238-, 2010

PubMed Abstract: GW182-family proteins are essential for microRNA-mediated translational repression and deadenylation in animal cells. Here we show that a conserved motif in the human GW182 paralog TNRC6C interacts with the C-terminal domain of polyadenylate binding protein 1 (PABC) and present the crystal structure of the complex. Mutations at the complex interface impair mRNA deadenylation in mammalian cell extracts, suggesting that the GW182-PABC interaction contributes to microRNA-mediated gene silencing.
