CC   -!- FUNCTION: ATP-dependent RNA helicase which is a subunit of the
CC       eIF4F complex involved in cap recognition and is required for mRNA
CC       binding to ribosome. In the current model of translation
CC       initiation, eIF4A unwinds RNA secondary structures in the 5'-UTR
CC       of mRNAs which is necessary to allow efficient binding of the
CC       small ribosomal subunit, and subsequent scanning for the initiator
CC       codon (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   -!- SUBUNIT: Component of the eIF4F complex, which composition varies
CC       with external and internal environmental conditions. It is
CC       composed of at least eIF4A, eIF4E and eIF4G (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC   -!- DOMAIN: The Q motif is unique to and characteristic of the DEAD
CC       box family of RNA helicases and controls ATP binding and
CC       hydrolysis.
CC   -!- SIMILARITY: Belongs to the DEAD box helicase family. eIF4A
CC       subfamily. {ECO:0000305}.
