WebJul 10, 2024 · The remodeling of stalled replication forks to form four-way DNA junctions is an important component of the replication stress response. Nascent DNA at the regressed arms of these reversed forks is protected by RAD51 and the tumor suppressors BRCA1/2, and when this function is compromised, stalled forks undergo pathological MRE11 … WebJan 4, 2024 · Another major pathway of fork protection is the shielding of stalled replication forks from inappropriate nuclease activity. In particular, the BRCA2 and RAD51 proteins prevent the MRE11 nuclease from degrading the nascent strand during replication stress (Schlacher et al., 2011, Schlacher et al., 2012). WebJan 1, 2024 · The original iPOND protocol ( Sirbu et al., 2012) calls for sonicating on ice with 20-s pulses followed by 40 s rests between pulses using a microtip sonicator on 13–16 W output, with the number of rounds depending on the sample volume. Successful solubilization is immediately observable by clarification of the lysate. edit emoji slack
