abstract：:Several components of translation, e.g. eIF4E and PKR, are implicated in cancer. The e-subunit (p48) of mammalian initiation factor 3 is encoded by the Int6 gene, a common site for integration of the mouse mammary tumor virus genome, leading to the production of a truncated eukaryotic initiation factor-3e (eIF3e).
