this study shows that 53BP1 is required for three-dimensional organization of the immunoglobulin heavy chain locus and provides a plausible explanation for the link with 53BP1 enforcement of deletional immunoglobulin class switch recombination
Genomic instability can be rescued by the deletion of Trp53bp1, which encodes the DNA damage response factor 53BP1, and mice expressing RING-less BRCA1 (show BRCA1 Antibodies) do not show an increased susceptibility to tumors in the absence of 53BP1.
Unlike directly induced DSBs, secondary DSBs were not efficiently repaired, although Rad51 (show RAD51 Antibodies) and 53BP1 were recruited to these sites. H2AX (show H2AFX Antibodies) was dramatically stabilized in response to DSBs directly caused by gamma-rays, enabling gammaH2AX (show H2AFX Antibodies) foci formation and DSB repair, whereas H2AX (show H2AFX Antibodies) was barely stabilized in response to secondary DSBs, in which gammaH2AX (show H2AFX Antibodies) foci were small and DSBs were not efficiently repaired
Study showed that mammalian cells use microtubules in the cytoplasm to promote the mobility of sites of DNA damage in the nucleus; molecular details of this process remain to be determined, the main players, including the MOB (show SGMS1 Antibodies) domain of 53BP1, the linker of the nucleoskeleton, and cytoskeleton complex, kinesins, and microtubules are now known, allowing further study.
These experiments define a novel requirement for 53BP1 in the fusions of DNA-PKcs (show PRKDC Antibodies)-deficient telomeres throughout the cell cycle.
Study concludes that only the 53BP1 status in DNA lesions, induced by UVA or gamma-rays, is affected by A-type lamin (show LMNA Antibodies) deficiency, which was not observed for heterochromatin-related proteins HP1beta (show CBX1 Antibodies) and BMI1 (show BMI1 Antibodies).
Binding of 53BP1 to methyl K810 occurs on E2 promoter binding factor (show E2F1 Antibodies) target genes and allows pRb (show PGR Antibodies) activity to be effectively integrated with the DNA damage response.
study uncovers novel ATM (show ATM Antibodies)-independent functions for 53BP1 in the suppression of oncogenic translocations and in radioprotection
Study concludes that 53BP1 promotes productive class switch recombination and suppresses mutagenic DNA repair through distinct phosphodependent interactions with RIF1 (show RIF1 Antibodies) and PTIP (show PAXIP1 Antibodies).
Thus, RIF1 and 53BP1 cooperate to block DSB resection to promote NHEJ in G1, which is antagonized by BRCA1 in S phase to ensure a switch of DSB repair mode to homologous recombination
It observed a distinct accumulation of 53BP1 protein to UV-induced DNA lesions: in R273C mutants, 53BP1 appeared transiently at DNA lesions, during 10-30 min after irradiation; the mutation R282W was responsible for accumulation of 53BP1 immediately after UVA-damage; and in L194F mutants, the first appearance of 53BP1 protein at the lesions occurred during 60-70 min.
A reciprocal regulation between 53BP1 and APC (show APC Antibodies)/C that is required for response to mitotic stress.
The authors identified 53BP1 and USP28 (show USP28 Antibodies) as essential components acting upstream of p53 (show TP53 Antibodies), evoking p21 (show CDKN1A Antibodies)-dependent cell cycle arrest in response not only to centrosome loss, but also to other distinct defects causing prolonged mitosis.
BRCA1 promotes PP4C (show PPP4C Antibodies)-dependent 53BP1 dephosphorylation and RIF1 (show INSL6 Antibodies) release, directing repair toward homologous recombination.
Co-localization of gammaH2AX (show H2AFX Antibodies) and 53BP1 indicates promotion of (in)effective nonhomologous end-joining repair mechanisms at sites of DSB. Moreover, gammaH2AX (show H2AFX Antibodies)/53BP1 foci distribution presumably reveals a non-random spatial organization of the genome in MDS (show PAFAH1B1 Antibodies) and AML (show RUNX1 Antibodies).
Results provide evidence that 53BP1 is involved in breast cancer cells resistance for PARP (show COL11A2 Antibodies) inhibitor; its depletion causes resistance in ATM (show ATM Antibodies)-deficient tumor cells.
Ubiquitin ligases RNF168 (show RNF168 Antibodies), RNF169 (show RNF169 Antibodies), and RAD18 (show RAD18 Antibodies) specifically bind histone H2A Lys13/15-ubiquitylated nucleosomes. 53BP1 chromatin recruitment may be activated by RNF168 (show RNF168 Antibodies) and blocked by RNF169 (show RNF169 Antibodies) and RAD18 (show RAD18 Antibodies).
53BP1 embodies two distinct activities: it can act as a DNA repair factor on the chromatin that flanks double-strand DNA repairs, and it promotes optimal p53 (show TP53 Antibodies) activity.
Ras-induced senescent cells are hindered in their ability to recruit BRCA1 and 53BP1 to DNA damage sites. Whereas BRCA1 is downregulated at transcripts levels, 53BP1 loss is caused by activation of cathepsin L-mediated degradation of 53BP1 protein. we discovered a marked downregulation of vitamin D receptor (VDR) during OIS, and a role for the vitamin D/VDR axis regulating the levels of these DNA repair
53BP1-USP28 (show USP28 Antibodies) cooperation is essential for normal p53 (show TP53 Antibodies)-promoter element interactions and gene transactivation-associated events, yet dispensable for 53BP1-dependent DNA double-strand repair regulation.
May have a role in checkpoint signaling during mitosis. Enhances TP53-mediated transcriptional activation. Binds to sites of DNA damage. Plays a role in the response to DNA damage (By similarity).
