10 Αυγ 2020 · In this paper we will review: (i) sources of the origin of uracil in DNA; (ii) some properties of the enzymes responsible for the excision of uracil and their role in the Ig diversification process, which comprises somatic hypermutation and class switch recombination; and (iii) consequences of cytosine deamination in other than the Ig loci, in ...
9 Σεπ 2008 · Genomic uracil is removed by uracil DNA glycosylases of base excision repair (BER). Unfortunately, BER is apparently problematic during thymidylate stress. Because BER requires a DNA resynthesis step, elevated dUTP causes reintroduction of genomic uracil.
9 Απρ 2021 · Here, we provide a summary of diverse uracil-DNA detection methods with their advantages and limitations, and discuss their results and conclusions. We detail the global quantitative U-detection methods as well as various emerging solutions for in situ uracil-DNA detection.

2 Φεβ 2016 · Genomic uracil is specifically recognized by representatives of the uracil-DNA glycosylase superfamily (UDG), cleaving the N-glycosidic bond between the pyrimidine ring and deoxyribose and resulting in apyrimidinic (AP) sites that are further processed by base excision repair ( 8, 9 ).
16 Δεκ 2002 · Uracil in DNA results from deamination of cytosine, resulting in mutagenic U : G mispairs, and misincorporation of dUMP, which gives a less harmful U : A pair. At least four different human DNA glycosylases may remove uracil and thus generate an abasic site, which is itself cytotoxic and potentially mutagenic.
