The roles of individual Eukaryotic translation Initiation Factor 3 (eIF3) subunits are largely unclear. Though some are essential, while others are thought to have regulatory roles. The "e" subunit, also known as Int-6, is a candidate for a regulatory subunit as it is not essential for translation initiation in yeasts. To further elucidate the roles of eIF3e, we have employed an interaction-tra...
