CC -!- FUNCTION: ATP-dependent RNA helicase involved in mRNA turnover, and
CC more specifically in mRNA decapping. Is involved in G1/S DNA-damage
CC checkpoint recovery, probably through the regulation of the
CC translational status of a subset of mRNAs. May also have a role in
CC translation and mRNA nuclear export (By similarity). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + H2O = ADP + H(+) + phosphate; Xref=Rhea:RHEA:13065,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616,
CC ChEBI:CHEBI:43474, ChEBI:CHEBI:456216; EC=3.6.4.13;
CC -!- SUBCELLULAR LOCATION: Cytoplasm, P-body {ECO:0000250}. Note=Is
CC concentrated in several cytoplasmic foci called P bodies (or
CC cytoplasmic processing bodies) which represent sites of mRNA decapping
CC and 5' to 3' exonucleotidic decay. {ECO:0000250}.
CC -!- DOMAIN: The Q motif is unique to and characteristic of the DEAD box
CC family of RNA helicases and controls ATP binding and hydrolysis.
CC -!- SIMILARITY: Belongs to the DEAD box helicase family. DDX6/DHH1
CC subfamily. {ECO:0000305}.
