Effect of TP53 on different DNA repair pathways; BER—base excision repair; NER—nucleotide excision repair; HR—homologous recombination; wt—wild-type.
TP53 Status | DNA Repair Pathway | Effect on DNA Repair | Citation |
---|---|---|---|
TP53 missense mutation | BER | APE1 regulation | [41] |
Hot-spot tumor-derived TP53 mutants | BER | Does not enhance activity of repair pathway in comparison with wt p53 | [39] |
Arg273His mutant TP53 | NER | Does not inhibit XPD (Rad3) and XPB DNA helicase activities in comparison with wt p53 | [47] |
p53 knock out | NER | Increase in chromosomal abnormalities | [48] |
R248W and R273H mutant TP53 | HR | Interaction with MRE11; inter-chromosomal translocations | [50] |
