摘要
Almost 20 years after the discovery of introns and RNA splicing, a second spliceosome was uncovered. Although this new spliceosome is structurally and functionally analogous to the well-characterized major-class splicing apparatus, it mediates the excision of a minor class of evolutionarily conserved introns that have non-canonical consensus sequences. This unanticipated diversity in the splicing machinery is refining both the mechanistic understanding and evolutionary models of RNA splicing.
