- TOPBP1 is a key player in DNA replication and DNA damage signaling. In this issue, Moudry et al. (2016. J. Cell Biol. http://dx.doi.org/10.1083/jcb.201507042) uncover a crucial role for TOPBP1 in DNA repair by revealing its requirement for RAD51 loading during repair of double strand breaks by homologous recombination.
