Single‐nucleotide editing: From principle, optimization to application

Abstract excerpt

Cytosine base editors (CBEs) and adenine base editors (ABEs), which are generally composed of an engineered deaminase and a catalytically impaired CRISPR-Cas9 variant, are new favorite tools for single base substitution in cells and organisms. In this review, we summarize the principle of base-editing systems and elaborate on the evolution of different platforms of CBEs and ABEs, including their deaminase, Cas9...
