What does this research mean for the field?

A specific 5-amino-acid segment in the U2 snRNP-B″ protein determines U2 RNA recognition specificity, while high-affinity binding to U2 RNA additionally requires the U2 snRNP-A′ protein as an accessory factor. Novelty: ClaimNovelty.NOVEL_FINDING. Consensus alignment: ConsensusAlignment.NEUTRAL.
