Abstract
The assembly of the DNA helicase at replication origins is crucial in initiating DNA synthesis. This process requires the conserved protein Cdt1. Here, a new study identifies a functional homologue of Cdt1 in Saccharomyces cerevisiae. The regulation of its activity reveals an alternative way to assemble prereplicative complexes (pre-RCs) and regulate origin function.
