A composite double-/single-stranded RNA-binding region in protein Prp3 supports tri-snRNP stability and splicing.

abstract：:How different helicase families with a conserved catalytic 'helicase core' evolved to function on varied RNA and DNA substrates by diverse mechanisms remains unclear. In this study, we used Mss116, a yeast DEAD-box protein that utilizes ATP to locally unwind dsRNA, to investigate helicase specificity and mechanism. Ou...
