DESCRIPTION

Also known as IF4A_YEAST, TIF1, TIF2, TIF41A, TIF41B. ATP-dependent RNA helicase which is a subunit of the eIF4F complex involved in cap recognition and is required for mRNA binding to ribosome. In the current model of translation initiation, eIF4A unwinds RNA secondary structures in the 5'-UTR of mRNAs which is necessary to allow efficient binding of the small ribosomal subunit, and subsequent scanning for the initiator codon. Component of the eIF4F complex, which composition varies with external and internal environmental conditions. It is composed of at least eIF4A (TIF1/TIF2), eIF4E (TIF45) and eIF4G (TIF4631 or TIF4632) (By similarity). Interacts with eIF4G1/TIF4631 and eIF4G2/TIF4632.
