(Submitter supplied) 53BP1 activity drives genome instability and embryonic lethality in BRCA1-deficient cells by inhibiting homologous recombination (HR).53BP1’s anti-recombinogenic functions require phosphorylation-dependent interactions with two effector complexes, PTIP and RIF1/Shieldin. While RIF1/Shieldin is thought to block 5’-3’ nucleolytic processing of DNA ends, it remains unclear how PTIP antagonizes HR. Here we show that mutation of the PTIP interaction site in 53BP1 (S25A) increases Shieldin association with DNA damage. more...
