Using a visualization technique called X-ray crystallography, the authors show that TIRR obstructs an area on 53BP1 that 53BP1 uses to bind chromosomes. But what shifts TIRR away from 53BP1, so the repair protein can work?

To identify regulatory factors of 53BP1 recruitment to chromatin, proteins associated with 53BP1-FFR were analyzed by mass spectrometry (Fig. 1a, b, Supplementary Table1).Based on percentage of coverage (47.0%) and the number of unique peptides (14), TIRR was one of the most abundant 53BP1-FFR …
WebJul 12, 2024 · 53BP1 performs essential functions in DNA double-strand break (DSB) repair and it was recently reported that Tudor interacting repair regulator (TIRR) negatively regulates 53BP1 during DSB repair. Here, we present the crystal structure of the 53BP1 tandem Tudor domain (TTD) in complex with TIRR. Web53BP1 (also called TP53BP1) is a chromatin-associated factor that promotes immunoglobulin class switching and DNA double-strand-break (DSB) repair by non-homologous end joining. To accomplish its...
WebAt the molecular level, TIRR interacts with the Tudor domain of 53BP1. This domain is involved in 53BP1 recruitment to the damaged chromatin by recognition of histone H4 dimethylated in lysine K20 (H4K20me2). 5 Structural evidence indicates that H4K20me2 and TIRR binding surfaces on 53BP1 Tudor domain overlap.
