A new genome-wide analysis of human kinases using RNA interference shows an unexpected depth and complexity to the interactions between these processes. Since the discovery in the nematode Caenorhabditis elegans that the introduction of a double-stranded RNA dsRNA trigger can lead to the selective inhibition of gene expression in a sequence-specific manner 1 this phenomenon - now widely known as RNA interference RNAi - has spawned many new applications. Among these is the invention of a whole area of genomics research dedicated to studying RNAi-induced phenotypes. Such phenotypes generally mimic reduction-of-function or loss-of-function mutations that have formed the backbone of traditional genetics research for more than a century. Most large-scale screens using this method have been performed in model organisms such as C. elegans 2-4 and Drosophila melanogaster 5 6 . As a result of recent insights into the mechanism of RNAi and the resulting identification of small interfering RNAs siRNAs such large-scale approaches are now also feasible in cultured mammalian cells 7 8 . The quantity of data derived from large-scale or whole-genome RNAi-based screens while sometimes overwhelming has begun to provide insights into complex biological phenomena that had previously proved .
