53BP1/Shieldin Counteract DSB Resection Through Fill-In Synthesis
… 53BP1 and its downstream effectors RIF1 and the shieldin complex limit the generation of long 3' overhangs at DSBs by recruiting CST/Polα to counteract resection, challenging the long-standing model of a block to resection by this pathway. Like loss of 53BP1/RIF1/shieldin, disruption of …

Interrogating DNA replication stress and DNA damage responses via phenotypic and functional CRISPR/Cas9 screens
… or alternatively the absence of the BRCA1-A complex. Accordingly, I establish that the catalytic activity of DNA ligase 4 (LIG4) is crucial for topotecan toxicity in Atm-/- cells and mutating the catalytic site of Lig4 reinstates cellular survival of ATM-deficient cells in the presence of …

53BP1 and double-strand break repair pathway choice in cancer
… other resistance mechanisms, we identified the shieldin complex (SHLD1/C20orf196 and SHLD2/FAM35A) that when lost suppressed PARP inhibitor sensitivity in BRCA1-deficient cancer cells. We demonstrate that SHLD1/2 represent the terminal end-effectors of the 53BP1-RIF1-MAD2L2 axis, supporting NHEJ …
