Abstract
eIF-4C has a pronounced stimulatory effect on initiation complex formation with native 80-S ribosomes (80-Sn) as the only source of ribosomal subunits, but only a small effect when washed 40-S subunits are used.
eIF-4C is accessary to eIF-3 in dissociating 80-Sn ribosomes.
eIF-4C is present on 40-Sn but absent on 40-Sn dimers,
