A pseudohelicase-centered complex couples assembly-dependent RNA cleavage to poly(UG)ylation

Robust RNA interference in Caenorhabditis elegans requires Argonaute targeted RNAs to be cleaved by RDE 8 and poly(UG)ylated by MUT 2, generating templates for RNA dependent RNA polymerases that synthesize secondary small RNAs. RDE 8 and MUT 2 are physically coupled within the cl...
