Function
DNA repair proteins correct DNA damage caused by mutations or toxins[1].
- DNA repair protein Rad4 is a yeast protein involved in DNA damage recognition in nucleotide excision repair[2]. Rad4 is an ortholog of the XPC protein. Rad4 opens up damaged DNA by inserting β-hairpin into the duplex and flipping out two damage-containing nucleotide pairs[3].
- DNA repair protein Rev1 is a DNA polymerase active in DNA damage sites. It contains 2 ubiquitin-binding sites[4].
- DNA repair protein Rad51 is a multifunctional protein with a role in DNA replication, homologous recombination repair and immunity[5].
- DNA repair protein Xrcc1 interacts with components of single-strand DNA breaks repair in mammalian cells[6].
- DNA repair protein Xrcc4 interacts with components of double-strand DNA breaks repair in mammalian cells[7].
- DNA repair protein PprA or Pleiotropic protein promoting DNA repair A facilitates the radiation resistance of Deinococcus radiodurans[8].
Relevance
DNA repair protein Rad51 is a potential marker for DNA repair in solid malignancies[9].
Disease
Mutations in DNA repair protein Rad4 can cause the xeroderma pigmentosum skin cancer predisposition syndrome[10].
