CLP1 plays an essential role in the protein complex involved in mRNA 3'-end formation and polyadenylation as well as in the tRNA splicing endonuclease (TSEN) complex involved in the splicing of precursor tRNAs. NOL9 localizes in the nucleolus of cells and plays an essential role in ribosomal RNA maturation. Both CLP1 and NOL9 are RNA kinases that phosphorylate the 5' end of RNAs. From the evidence that phosphorylation of the 5' end of a siRNA is essential for its efficient RNA cleavage, it was expected that CLP1 and NOL9
