abstract：:The U2 snRNP promotes prespliceosome assembly through interactions that minimally involve the branchpoint binding protein, Mud2p, and the pre-mRNA. We previously showed that seven proteins copurify with the yeast (Saccharomyces cerevisiae) SF3b U2 subcomplex that associates with the pre-mRNA branchpoint region: Rse1p,...
