eIF4A1(Eukaryotic translation initiation factor 4A1) also known as DDX2A is a member of the eukaryotic initiation factor-4A (eIF4A) family. eIF4A1 is a core component of the eIF4F translation initiation machinery that unwinds structured 5′ UTRs to enable ribosome scanning and efficient cap-dependent translation. eIF4A1 enables double-stranded RNA binding activity and translation initiation factor activity. Involved in cytoplasmic translational initiation and positive regulation of transcription by RNA polymerase II. By coupling ATP-dependent RNA remodeling to initiation complex assembly, eIF4A1 helps regulate proteome output downstream of growth and stress signaling pathways that shape translational control.
