KeyGene reference: P200


The invention relates to genome editing using cysteine or adenine deaminase fused to a site-specific nuclease such as an RNA-guided CRISPR-CAS protein. These fusion proteins allow the precise conversion of single nucleotides in single targeted locus of the genome. Using a combination of two fusion proteins effectively directs the simultaneous conversion of both a cytosine and an adenine in a single locus.


Genome editing technologies are rapidly emerging. The present invention allows for a highly precise orchestration of nucleotide conversions. The fusion proteins of the invention, and combined working thereof, contribute to the endless options of nucleotide changes that can be achieved with available genome editing tools.


Understanding the function of genes is essential for efficient breeding of improved crops. Efficient targeted genome editing technologies are important research tools in gene validation and may be used for introduction of new traits in crop germplasm. The present invention contributes thereto.
