WebThe base editor binds the target DNA and exposes a narrow editing window. The deaminase then makes the desired edit to a target base. We believe that the modular … WebMar 27, 2024 · During cytosine base editing, the uracil deaminated from targeted cytidine could be repaired to form C-to-T conversion [3]. However, uracil can also be transformed into an apurinic/apyrimidinic (AP) site by uracil DNA glycosylase (UDG), which results in InDels by triggering NHEJ repair or unintended C-to-A or C-to-G substitutions through ...

The engineered PmCDA1 (tCDA1EQ) is substantially smaller (121 a.a.) in size compared to the wild-type (208 a.a.). Smaller molecular size as a genome editing component is advantageous especially for in vivo delivery tools. Therefore, we introduced the small ortholog SaCas9 system to minimize the size … See more Next, we evaluated the editing efficiency and window of AID-2S and AID-3S in human HEK293T cells and compared them with existing improved cytosine base editors YE1, YE2, and R33A + K34A that were reported to … See more Both DNA and RNA off-target effect has been the issue for base editing as well. Intrinsically, APOBEC-based base editors have RNA editing capacity which causes gRNA-independent and gRNA-dependent RNA off-target … See more WebApr 4, 2024 · Editing of the eye pigmentation gene oca2 with cytosine or adenine base editors in F0 yielded high on-target editing (79%) and editor dependent low to moderate levels of indels (8–14%).
