Eukaryotic translation initiation factor 4A, isoform 3, also known as eIF4A3, is a member of the DEAD box protein family. DEAD box proteins are characterized by the conserved motif Asp-Glu-Ala-Asp (DEAD). This family of proteins are putative RNA helicases and are implicated in a number of cellular processes involving alteration of RNA secondary structure, such as translation initiation, nuclear and mitochondrial splicing, and ribosome and spliceosome assembly. Based on their distribution patterns, some members of this family are believed to be involved in embryogenesis, spermatogenesis, and cellular growth and division. eIF4A3 is a nuclear matrix protein. Its amino acid sequence is highly similar to the amino acid sequences of the translation initiation factors eIF4AI and eIF4AII, two other members of the DEAD box protein family.
