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: eIF4F is a multi-subunit complex, the composition of which
CC varies with external and internal environmental conditions. It is
CC composed of at least EIF4A, EIF4E and EIF4G1/EIFFG3 (By similarity).
CC Interacts with EIF4E. May interact with NOM1 (By similarity).
CC {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the DEAD box helicase family. eIF4A subfamily.
CC {ECO:0000305}.
