UHRF1 (ubiquitin-like, containing PHD and RING finger domains 1) has a well-established role in epigenetic regulation through the recognition of various histone marks and interaction with chromatin-modifying proteins. However, its function in regulating cell cycle progression remains poorly understood and has been largely attributed to a role in transcriptional regulation. In this study we have used Xenopus laevis egg extracts to analyse Uhrf1 function in DNA replication in the absence of transcriptional influences. We demonstrate that removal of Uhrf1 inhibits chromosomal replication in this system. We further show that this requirement for Uhrf1, or an associated factor, occurs at an early stage of DNA replication and that the consequences of Uhrf1 depletion are not solely due to its role in loading Dnmt1 onto newly replicated DNA. We describe the pattern of Uhrf1 chromatin association before the initiation of DNA replication and show that this reflects functional requirements both before and after origin licensing. Our data demonstrate that the removal of Xenopus Uhrf1 influences the chromatin association of key replication proteins and reveal Uhrf1 as an important new factor required for metazoan DNA replication.
