Abstract excerpt

Eukaryotic translation initiation factor 3 (eIF3) consists of core subunits that are conserved from yeast to man as well as less conserved, noncore, subunits with potential regulatory roles. Whereas core subunits tend to be indispensable for cell growth, the roles of the noncore subunits remain poorly understood. We addressed the hypothesis that eIF3 noncore subunits have accessory functions that help to regulate...
