Eukaryotic translation initiation factor 1 (eIF1) is a protein that in humans is encoded by the EIF1 gene.[2][3][4]

eIF1 interacts with the eukaryotic small (40S) ribosomal subunit and eIF3, and is a component of the 43S preinitiation complex (PIC).[5] eIF1 and eIF1A bind cooperatively to the 40S to stabilize an "open" conformation of the preinitiation complex (PIC) during eukaryotic translation initiation.[5] eIF1 binds to a region near the ribosomal A-site in the 40S subunit and functions in a manner similar to the structurally related bacterial counterpart IF1.[6]
