RDE-4 was identified through a genome-wide screening as a gene responsible for greatly reducing or abolishing RNAi in C. elegans. In organisms ranging from Arabidopsis to humans, Dicer requires dsRNA-binding proteins (dsRBPs) to carry out its roles in RNA interference (RNAi) and micro-RNA (miRNA) processing. In Caenorhabditis elegans, the dsRBP RDE-4 acts with Dicer during the initiation of RNAi, when long dsRNA is cleaved to small interfering RNAs (siRNAs). RDE-4 is not sequence-specific, however, RDE-4 binds with higher affinity to long dsRNA. Interestingly, RDE- 4 is the only protein that exhibits micromolar affinity for dsRNA in the absence of co-operativity. In addition, RDE-4 is a homodimer in solution. <ref name=first>DOI: 10.1261/rna.2338706</ref> (Yellow Citation) | RDE-4 was identified through a genome-wide screening as a gene responsible for greatly reducing or abolishing RNAi in C. elegans.
