Application

4E1RCat was used to inhibit new protein synthesis in transformed primary chicken embryo fibroblasts.[1]

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.
4E1RCat is an inhibitor of translation initiation complex eIF4F

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

Cancer persister cells tolerate anticancer drugs and serve as the founders of acquired resistance and cancer relapse. Here we show that a subpopulation of BRAFV600 mutant melanoma cells that tolerates exposure to BRAF and MEK inhibitors undergoes a reversible remodelling
