evidence for variation in the optimal translation initiation complex: plant eif4b, eif4f, and eif(iso)4f differentially promote translation of mrnas.eukaryotic initiation factor (eif) 4b is known to interact with multiple initiation factors, mrna, rrna, and poly(a) binding protein (pabp). to gain a better understanding of the function of eif4b, the two isoforms from arabidopsis (arabidopsis thaliana) were expressed and analyzed using biophysical and biochemical methods. plant eif4b was found by ultracentrifugation and light scattering analysis to most likely be a monomer with an extended structure. an extended structure would facilitate the ...200919493973
