WebJan 1, 2009 · The DEAD-box protein Ded1p/DDX3 is conserved from yeast to human. Various lines of genetic and biochemical evidence have indicated a role of the yeast Ded1p in translation and, most likely, in precursor mRNA splicing as well. In contrast, although recent studies have begun to reveal the function of the mammalian DDX3 in translation … Webrecombinant Ded1p was used to test the role of Ded1p in TBSV replication. We define that Ded1p plays a role in enhancing plus-strand (+)RNA synthesis by the viral replicase. We also find that Ded1p is a component of the tombusvirus VRC and binds to the 39-end of the viral minus-stranded (2)RNA. The obtained data

DEAD-Box Proteins Unwind Duplexes by Local Strand Separation

WebAug 20, 2015 · Here we show that the DEAD-box helicase Ded1p oligomerizes in the cell and in vitro, and unwinds RNA as a trimer. Two protomers bind the single-stranded region of RNA substrates and load a third protomer to the duplex, which then separates the strands. ATP utilization differs between the strand-separating protomer and those bound to the … WebJan 24, 2024 · How Ded1p and its orthologs engage RNAs to impact translation initiation has been a longstanding, unresolved question. Here we show that Ded1p associates with the pre-initiation complex at the mRNA entry channel of the small ribosomal subunit and that the helicase unwinds mRNA structure ahead of the scanning pre-initiation complex. …
