Biochem/physiol Actions

Eukaryotic translation initiation factor 4E is a protein encoded by the EIF4E gene in humans. It is located on human chromosome 20. High level of eIF4E is associated with an increased risk for systemic metastasis in node-positive breast cancer. eIF4E over expression is also associated with a higher incidence of metastasis to multiple sites and acts as a marker for molecular events that increases risk for systemic dissemination. It is also involved in maintaining cell proliferation.
