Background:
4E1RCat is a dual inhibitor of eIF4E:4E-BP1 and eIF4E:eIF4G interaction, and inhibits the binding of eIF4G to eIF4E with IC50 of 3.2 μM.
The complexity of eIF4A, eIF4E and eIF4G together forms the eIF4F, the eukaryotic initiation factor, which stimulates the loading of ribosomes onto mRNA templates in protein synthesis. The inhibition of this cap-dependent translation is associated with cancer initiation and progression [1].
4E1RCat prevents assembly of the eIF4F complex and inhibits cap-dependent translation [1]. 4E1RCat significantly inhibited 5′-cap-mediated mCherry synthesis while had little effect on the IRES-mediated DIAPH1-HA synthesis, which confirmed the specific inhibitory effect of 4E1RCat on 5′-cap-mediated translation [2].
