Application

4E1RCat was used to inhibit new protein synthesis in transformed primary chicken embryo fibroblasts.

Biochem/physiol Actions

4E1RCat ilnhibits the eIF4F translation initiation complex by binding to IF4E b and inhibiting the interaction between IF4E:eIF4G (IC50 = 3.2 μM). In in vitro translation experiments using MDA-MB-231 cells, 4E1RCat dose dependently inhibited cap-dependent translation, led to a decrease in polysome and 80S ribosomal subunits and reduced levels of the eIF4F-dependant proteins Mcl-1 and c-Myc.

DIAPH1 is a formin protein which promotes actin polymerization, stabilizes microtubules and consequently is involved in cytoskeleton dynamics, cell migration and differentiation. In contrast to the relatively well-understood signaling cascades that regulate DIAPH1 activity, its spatial regulation of biogenesis is
