Base editors, such as cytosine and adenine base editors, are composed of nickase Cas9 (nCas9) and deaminase and serve as Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-based enzymatic tools for specific nucleotide substitutions. They are mainly the most effective genome editing tools for introducing point mutations, such as C-to-T and A-to-G conversions. The enhanced base editor, a C-to-G base editor (CGBE), can perform other nucleotide substitutions, such as C-to-G conversions. Here, we introduce a method for generating mouse models with point mutations using a base editing system.
Keywords: Adenine base editor; CRISPR system; Cytosine base editor; Mouse model generation; Nucleotide substitution; Targeted mutagenesis.
