WebNov 24, 2024 · For Ded1p, rate constants for strand separation are only slightly higher for 3′-tailed substrates, compared to those with a 5′ tail [34]. Since functional affinities of DDX3X for 3′ and 5′-tailed substrates are similar, we speculate that unwinding of 5′-tailed substrates by DDX3X is associated with an energy penalty at the strand ... 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

WebMar 7, 1997 · The DED1 gene was originally identified as an essential open reading frame adjacent to HIS3 ( 6 ). Ded1p was hypothesized to function in nuclear pre-mRNA splicing … WebDed1p leads to ATIS activation in 5′ UTRs, which decreases polysome formation on the main ORFs and thereby overall protein production. We conclude that Ded1p function suppresses the use of ATISs.
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 … WebApr 30, 2024 · Ded1p-mRNA condensates initially exhibited liquid-like properties but hardened after a few minutes of heating (Figure 4E; Video S1).

WebMay 13, 1997 · So far, no other data concerning the function of Ded1p have been reported. Our results demonstrate that Ded1p is involved in translation initiation. DED1 is a multicopy suppressor of different cdc33 alleles and tif1–1. Furthermore, the ded1/spp81–3 allele is synthetically lethal with some translation initiation factor mutants.
