    ..Together, our findings provide evidence that hRAD51-ATP filaments can exist in two interconvertible conformational states, which might be functionally relevant for DNA homology recognition and strand exchange. ..

    ..In this issue of Structure, Grabarczyk et al. (2018) reveal that a hook-like structure formed by the unique Dcc1 and Ctf8 subunits mediates the interaction of Ctf18-RFC with the leading strand DNA polymerase ɛ. ..

    ..These results indicate that Brca2 and Rad51 prevent formation of abnormal DNA replication intermediates, whose processing by Smarcal1 and Mre11 predisposes to genome instability. ..

    ..Most strikingly, Ctf4-dependent recruitment of CIP-box proteins couples other processes to DNA synthesis, including rDNA copy-number regulation. ..

    ..The CMG helicase of the last archaeal/eukaryotic ancestor might have harboured a single-stranded DNA nuclease activity, conserved in some modern archaea. ..

    ..Our findings provide a biochemical basis for the specific interaction between two critical components of the human replisome, and indicate that important principles of replisome architecture have changed significantly in evolution. ..

    ..Our evidence shows that PriX has replaced PriL as the subunit that endows primase with the unique ability to initiate nucleic acid synthesis. Importantly, our findings reveal that the Fe-S cluster is not required for primer synthesis. ..
