RNAi Curation Mission Summary
The term "RNAi" stands for "RNA-interference" and refers to the targeted silencing of gene expression of a "target gene" via introduction of double stranded RNA (dsRNA) containing high degrees of sequence identity to the "target gene". In C. elegans, sequences of dsRNA may be introduced into the worm by a variety of different methods including direct micro-injection, soaking of worms in solution containing dsRNA, feeding worms bacteria that express dsRNA from a plasmid, and transgenic expression (within the worm) of dsRNA. For efficient and specific knockdown of gene expression, the dsRNA must have a minimum sequence identity with the target gene sequence. Any phenotype(s) resulting from the RNAi-mediated knockdown of a particular gene is thought to directly reflect the phenotype of a loss-of-function mutation in that gene, hence providing evidence as to the gene's biological function.
The goal of RNAi curation is to associate RNAi-mediated phenotypes with the target genes knocked down in RNAi experiments, as found in the literature pertaining to C. elegans and related species.
