Motoring toward pre-60S-ribosome export

Rea1 is an ATPase related to dynein motor proteins that has been implicated in the biogenesis of the 60S ribosomal subunit. A new cryo-EM study vividly demonstrates the power of structural methods, deciphering the role of Rea1 in monitoring key pre-60S maturation steps before the acquisition of export competence in budding yeast.
