The N-terminal domain of Ded1p contains RGG repeats, which have been shown in other proteins to bind quadruplex structures.18 The helicase domain is also likely involved in G4DNA binding because DN Ded1p retains some G4DNA binding activity.

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. WebJan 1, 2009 · The DEAD-box protein Ded1p/DDX3 is conserved from yeast to human.
