[[http://www.uniprot.org/uniprot/BRR2_YEAST BRR2_YEAST]] RNA helicase that plays an essential role in pre-mRNA splicing as component of the U5 snRNP and U4/U6-U5 tri-snRNP complexes. Involved in spliceosome assembly, activation and disassembly. Mediates changes in the dynamic network of RNA-RNA interactions in the spliceosome. Catalyzes the ATP-dependent unwinding of U4/U6 RNA duplices, an essential step in the assembly of a catalytically active spliceosome.<ref>PMID:19098916</ref> <ref>PMID:23124065</ref> <ref>PMID:19716790</ref> <ref>PMID:19525970</ref>
