    ..A very weak effect of SWI/SNF on the 8-oxoG BER removal in H2A.Bbd histone variant nucleosomes was observed. The possible implications of our data for the understanding of in vivo mechanisms of BER are discussed. ..

    ..Peculiar features of the expression of this gene, including an unusual splicing variability and a splicing inhibition in response to DNA-damaging agents, are discussed. ..
  3. Villani G, Hubscher U, Gironis N, Parkkinen S, Pospiech H, Shevelev I, et al. In vitro gap-directed translesion DNA synthesis of an abasic site involving human DNA polymerases epsilon, lambda, and beta. J Biol Chem. 2011;286:32094-104 pubmed publisher
    ..Collectively, our in vitro results support the existence of a mechanism of gap-directed TLS at an AP site involving a switch between the replicative pol ? and the repair pols ? and ?. ..
  4. Aoufouchi S, Flatter E, Dahan A, Faili A, Bertocci B, Storck S, et al. Two novel human and mouse DNA polymerases of the polX family. Nucleic Acids Res. 2000;28:3684-93 pubmed
    ..This suggests that their biological function may differ from DNA translesion synthesis, for which several DNA polymerase activities have been recently described. Possible functions are discussed. ..
  5. Pélissier T, Clavel M, Chaparro C, Pouch Pélissier M, Vaucheret H, Deragon J. Double-stranded RNA binding proteins DRB2 and DRB4 have an antagonistic impact on polymerase IV-dependent siRNA levels in Arabidopsis. RNA. 2011;17:1502-10 pubmed publisher
    ..Moreover, transgenic plants overexpressing DRB2 mimicked drb4 mutants at the morphological and molecular levels, confirming the antagonistic roles of DRB2 and DRB4. ..
  6. Goula A, Berquist B, Wilson D, Wheeler V, Trottier Y, Merienne K. Stoichiometry of base excision repair proteins correlates with increased somatic CAG instability in striatum over cerebellum in Huntington's disease transgenic mice. PLoS Genet. 2009;5:e1000749 pubmed publisher
    ..We propose that the stoichiometry of BER enzymes is one critical factor underlying the tissue selectivity of somatic CAG expansion. ..
  7. Wagner J, Etienne H, Fuchs R, Cordonnier A, Burnouf D. Distinct beta-clamp interactions govern the activities of the Y family PolIV DNA polymerase. Mol Microbiol. 2009;74:1143-51 pubmed publisher
    ..This discloses two independent modes of action for PolIV and, in turn, uncovers a novel way by which the cell may regulate the potentially deleterious effect of such low fidelity polymerases during replication. ..
  8. Emond S, Mondon P, Pizzut Serin S, Douchy L, Crozet F, Bouayadi K, et al. A novel random mutagenesis approach using human mutagenic DNA polymerases to generate enzyme variant libraries. Protein Eng Des Sel. 2008;21:267-74 pubmed publisher
    ..By taking advantage of the mutation bias of naturally highly error-prone DNA polymerases, MutaGen thus appears as a very useful tool for gene and protein randomisation. ..
  9. Bjedov I, Dasgupta C, Slade D, Le Blastier S, Selva M, Matic I. Involvement of Escherichia coli DNA polymerase IV in tolerance of cytotoxic alkylating DNA lesions in vivo. Genetics. 2007;176:1431-40 pubmed
    ..This activity is of major biological relevance because alkylating agents are continuously produced endogenously in all living cells and are also present in the environment. ..
