Abstract
Replication fork reversal is a rapidly emerging and remarkably frequent mechanism of fork stabilization in response to genotoxic insults. Here, we summarize recent findings that uncover key molecular determinants for reversed fork formation and describe how the homologous recombination factors BRCA1, BRCA2, and RAD51 protect these structures from extended nucleolytic degradation. Replication fork reversal is a central mechanism of fork stabilization. Quinet et al. review recent findings on the mechanisms of reversed fork formation and on the role of key homologous recombination factors in protecting reversed forks from nucleolytic degradation.
