WebMay 1, 2024 · In summary, our results showed that generally, 53bp1 is not recruited to DSB repair foci positive for phosphorylated H2AX in the ONL and INL, but only occasionally co-localizes. In the INL and GCL, many … WebApr 4, 2002 · These pleiotropic phenotypes were associated with chromosomal instability, repair defects, and impaired recruitment of Nbs1, 53bp1, and Brca1, but not Rad51, to irradiation-induced foci. Thus, H2AX is critical for facilitating the assembly of specific DNA-repair complexes on damaged DNA.

Web53BP1 is underexpressed in most cases of triple-negative breast cancer. [8] DNA repair [ edit] DNA double-strand breaks (DSBs) are cytotoxic damages that can be repaired either by the homologous recombinational repair (HR) pathway or by the non-homologous end-joining (NHEJ) pathway. NHEJ, although faster than HR, is less accurate. WebApr 14, 2024 · The downstream proteins of RNF8, RAD18 (RAD18 E3 ubiquitin protein ligase), and 53BP1(transformation-related protein 53-binding protein 1) are localized to the entire sex chromosomes (van der Laan et al., 2004). However, it has been reported that either RAD18 or 53BP1 does not affect fertility in mice (Ward et al., 2003; Sun et al., 2009).
