SCML2 inhibits PrimPol-mediated DNA replication repriming and regulates replication gap-associated cancer cell vulnerability
PrimPol-mediated fork repriming generates single-stranded DNA (ssDNA) gaps during DNA damage tolerance (DDT), which, if not properly repaired, can threaten genomic stability. PrimPol is a highly error-prone polymerase. Thus, PrimPol activity should be tightly regulated to fit into DDT and remain low during unstressed D...
