The evolution of the ribosome biogenesis pathway from a yeast perspective.

abstract：:During the splicing process, spliceosomal snRNAs undergo numerous conformational rearrangements that appear to be catalyzed by proteins belonging to the DEAD/H-box superfamily of RNA helicases. We have cloned a new RNA helicase gene, designated DBP2 (DEAH-boxprotein), homologous to the Schizosaccaromyces pombe cdc28(+...
