CC -!- FUNCTION: ATP-dependent RNA helicase. Binds to partially double-
CC stranded RNAs (dsRNAs) in order to unwind RNA secondary structures.
CC Unwinding is promoted in the presence of single-strand binding
CC proteins. Mediates also RNA duplex formation thereby displacing the
CC single-strand RNA binding protein. ATP and ADP modulate its activity:
CC ATP binding and hydrolysis by DDX42 triggers RNA strand separation,
CC whereas the ADP-bound form of the protein triggers annealing of
CC complementary RNA strands. {ECO:0000250|UniProtKB:Q86XP3}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + H2O = ADP + H(+) + phosphate; Xref=Rhea:RHEA:13065,
