Clinical significance
53BP1 is underexpressed in most cases of triple-negative breast cancer.[8]
DNA repair
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. The early divergent step between the two pathways is end resection, and this step is regulated by numerous factors. In particular, BRCA1 and 53BP1 play a role in determining the balance between the two pathways.[9][10] 53BP1 restricts resection and promotes NHEJ.
Trimethylated histone H4 at lysine 20 (H4K20me3) functions in DNA repair as a binding site for 53BP1.[11] The cellular level of H4K20me3 is increased by DNA damaging radiation. Another trimethylated histone, H3K9me3, also interacts with 53BP1. In addition, H4K20me2 and H3K79me2 facilitate the recruitment of 53BP1 to chromatin in the vicinity of a DNA double-strand break. Thus H4K20me3, H3K9me3, H4K20me2 and H3K79me2 are epigenetic markers that are important for the function of the 53BP1 in NHEJ repair of DNA double-strand breaks.
Interactions
53BP1 has been shown to physically interact with:
Histone H4 dimethylated or monomethylated at Lysine 20[12]
p53[13][14][15][16]
DYNLL1[17]
