Functional characterization of the putative Aspergillus nidulans DNA damage binding protein homologue DdbA
(SPRINGER, 2008)
Nucleotide excision repair (NER) eliminates helix-distorting DNA base lesions. Seven XP-deficient genetic complementation groups (XPA to XPG) have already been identified in mammals, and their corresponding genes have been ...
A radiação ultravioleta nos ecossistemas aquáticos e seus impactos nas diferentes espécies: uma revisão bibliográfica
(Universidade Federal de Minas GeraisUFMG, 2013-03-16)
During the last years, it was observed a great reduction in the thickness of the ozone layer and thereby become visible effects caused by incidence of ultraviolet rays. The increase of deforestation and erosion, are ...
Divergent functions of the Arabidopsis mitochondrial SCO proteins: HCC1 is essential for COX activity while HCC2 is involved in the UV-B stress response
(Frontiers, 2014-03)
The two related putative cytochrome c oxidase (COX) assembly factors HCC1 and HCC2 from Arabidopsis thaliana are Homologs of the yeast Copper Chaperones Sco1p and Sco2p. The hcc1 null mutation was previously shown ...
Genetic interactions of the Ashergillus nidulans atmA(ATM) homolog with different components of the DNA damage response pathway
(GENETICS, 2008)
Ataxia telangiectasia mutated (ATM) is a phosphatidyl-3-kinase-related protein kinase that functions as a central regulator of the DNA damage response in eukaryotic cells. In humans, mutations in ATM cause the devastating ...
The interplay of UV and cutaneous papillomavirus infection in skin cancer development
(Public Library Of Science, 2017-11)
Cutaneous human papillomaviruses (HPVs) are considered as cofactors for non-melanoma skin cancer (NMSC) development, especially in association with UVB. Extensively studied transgenic mouse models failed to mimic all aspects ...
Identification of regulatory elements involved in expression and induction by sucrose and UV-B light of the Arabidopsis thaliana COX5b-2 gene, encoding an isoform of cytochrome c oxidase subunit 5b
(Wiley Blackwell Publishing, Inc, 2009-11)
The promoter sequences required for expression of the Arabidopsis thaliana COX5b-2 gene, encoding an isoform of cytochrome c oxidase subunit 5b, were analyzed using plants transformed with deleted and mutagenized forms of ...
Communication: UV photoionization of cytosine catalyzed by Ag+
(American Institute of Physics, 2015-07)
The photo-induced damages of DNA in interaction with metal cations, which are found in various environments, still remain to be characterized. In this paper, we show how the complexation of a DNA base (cytosine (Cyt)) with ...
Deletion mapping of the potyviral helper component-proteinase reveals two regions involved in RNA binding
(Academic Press IncSan DiegoEUA, 2000)
