Cytosine base editors
WebSep 23, 2024 · Current cytosine or adenine base editors can only accomplish C-to-T (G-to-A) or A-to-G (T-to-C) substitutions in the windows of target genomic sites of organisms; therefore, there is a need to develop base editors that can simultaneously achieve C-to-T and A-to-G substitutions at the targeting site. Results WebSep 3, 2024 · Cytosine and adenine base editors (CBEs and ABEs), which produce highly efficient targeted point mutations in genomic DNA without causing double-stranded DNA breaks, have been used in therapeutic (Chadwick et al., 2024; Liang et al., 2024; Ryu et al., 2024 ), agricultural ( Li et al., 2024; Xue et al., 2024; Zhang et al., 2024 ), and research …

WebWe describe base editors that combine both cytosine and adenine base-editing functions. A codon-optimized fusion of the cytosine deaminase PmCDA1, the adenosine deaminase TadA and a Cas9 nickase (Target-ACEmax) showed a high median simultaneous C-to-T and A-to-G editing activity at 47 genomic targets. On-target as well as DNA and RNA off …
WebCBEs were first reported by Liu and co-workers in 2016 , and base editor 1 (BE1) was developed by fusing a naturally existed cytidine deaminase rAPOBEC1 to dCas9 (Cas9 variants containing both D10A and H840A mutations). rAPOBEC1 catalyzes cytosine (C) deamination into uracil (U), which is recognized as thymine (T) in base-pairing process; … WebMar 13, 2024 · Cytosine base editors go off-target.
