WebJan 7, 2024 · 53BP1 controls two downstream sub-pathways, one mediated by PTIP and Artemis and the other by RIF1 and MAD2L2/Shieldin, to coordinate DNA repair pathway choices. However, the upstream regulator (s) of 53BP1 function in DNA repair remain unknown. We and others recently reported that TIRR associates with 53BP1 to stabilize it … WebMay 6, 2024 · 53BP1 influences genome stability via two independent mechanisms: (1) regulating DNA double-strand break (DSB) repair and (2) enhancing p53 activity. We discovered a protein, Tudor-interacting repair regulator (TIRR), that associates with the 53BP1 Tudor domain and prevents its recruitment to DSBs.
