WebCytosine base editing. (a)Cytosine deamination generates uracil, which base pairs as thymidine. R = 2′-deoxyribose in DNA, or ribose in RNA. (b)Cytosine base editing strategy by BE1, BE2, BE3, or BE4. R-loop formation exposes a region of single-stranded DNA to the cytidine deaminase domain. WebJul 2, 2024 · Adenine base editors (ABEs) catalyze A-to-G conversions at genomic sites of interest. However ABEs also induce cytidine deamination. We engineered ABEs to reduce the cytosine editing activity of them. This behind the paper post covers our recent work on development of more precise base editors. WebResults Here, we compared the gene disruption by CBE﹎ediated iSTOP with CRISPR/Cas9﹎ediated frameshift. We found BE﹎ediated gene knockout yielded fewer genotypes. BE﹎ediated gene editing precisely achieved silencing of two neighbouring genes, while CRISPR/Cas9 may delete the large fragment between two target sites. fnf shakey notes event
