CC -!- FUNCTION: ATP-dependent RNA helicase which is a subunit of the eIF4F
CC complex involved in cap recognition and is required for mRNA binding to
CC ribosome. In the current model of translation initiation, eIF4A unwinds
CC RNA secondary structures in the 5'-UTR of mRNAs which is necessary to
CC allow efficient binding of the small ribosomal subunit, and subsequent
CC scanning for the initiator 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 with
CC external and internal environmental conditions. It is composed of at
CC least eIF4A, eIF4E and eIF4G (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {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. eIF4A subfamily.
CC {ECO:0000305}.
