The EIF1 protein is a key member of the 43S preinitiation complex (43S PIC), binding to the mRNA cap-proximal region, scanning the 5′-untranslated region, and localizing the initiation codon. EIF1 Protein, Human (GST) is the recombinant human-derived EIF1 protein, expressed by E. coli , with N-GST labeled tag.
