Abstract

This entry represents the DEAD/DEAH box helicase domain found in Ded1 and its paralog, Dbp1, from yeasts, which contains the ATP-binding region. Ded1 and Dbp1 are ATP-dependent DEAD-box RNA helicases involved in eIF4F-dependent 48S translation preinitiation complex (PIC) assembly [ 1 , 2 ]. This entry also includes Drosophila melanogaster Vasa, which is essential for development [ 3 ].
