This Protocol leverages prime editing to insert recombinase recognition sites into repetitive genomic regions, such as LINE-1 elements, thereby enabling extensive genetic modifications in human cells, and supports a wide range of studies, including genome-wide functional analyses and essentiality mapping.
An RNA-guided bridge recombinase system is engineered through rational mutagenesis and AI-assisted directed evolution, enabling programmable chromosomal rearrangements in both plant and mammalian cells and achieving up to a 29.8-fold increase in activity.

Genomic manipulation has advanced from stochastic nuclease‐mediated disruption toward programmable, deterministic precision. Early clustered regularly interspaced short palindromic repeats (CRISPR) strategies enabled targeted mutagenesis through double‐strand breaks; however, their therapeutic application is limited by...
To systematically map cellular factors constraining nonviral genome editing, influencing uptake and intracellular trafficking, we develop a genome-wide CRISPR screening platform linking perturbation of 19,114 genes to editing outcomes in human cells. We identify six negative regulators of delivery whose depletion incre...

A novel genome-wide CRISPR screening strategy that will facilitate the systematic engineering of novel nonviral genome editing delivery methods, where the identified novel gene hits can be further used to increase editing efficiency for other therapeutically relevant cell types.

Using high-throughput junction mapping together with large-scale comparative genomics, this work redefined the in vivo structural boundaries, growth, and mobilization of IS110 elements and uncovered a previously unrecognized size continuum extending to ∼100 kb, driven by progressive additions.
