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; … WebJul 2, 2024 · Previous cytosine base editors have great editing efficiency, however their great activity also affects neighboring cytosine bases within the editing window. As the previous ABE has a specific motif for cytidine deamination, we thought that a new cytosine base editor based on ABE would specifically catalyze TC-to-TT, or TC-to-TG. We found …
