Described herein are methods and compositions for genomic editing. Endonucleases for genomic editing involve inducing breaks in double stranded DNA, for which knock-ins are notoriously inefficient for relying on random integration of homologous DNA sequences into the break site by repair proteins. To address these issues, described herein are novel recombinant fusion proteins that actively recruit linear DNA inserts in closer proximity to the genomic cleavage site, increasing integration efficiency of large DNA fragments into the genome. Such improvements to genomic editing technology allow one to use lower linear DNA concentrations without sacrificing efficiency and can be further combined with other features, such as fluorescent protein reporting systems.

Optimized gene editing utilizing a recombinant endonuclease system

Provided are compositions and methods for labeling an endogenous protein, in particular, in a live cell, or for ablating an endogenous or target protein. The compositions relate to a fusion protein having a binding moiety such as an antibody, an antigen binding fragment of an antibody or an antibody mimetic that recognizes the endogenous or target protein.
