AI Technical Summary
Existing technologies struggle to achieve site-specific integration of large serine recombinases into the human genome, and existing methods are time-consuming, labor-intensive, and carry the risk of off-target events.
Multiple variants were generated by mutating large serine recombinases (LSRs), and their target site specificity was optimized by expressing and screening them in host cells using expression vector libraries. Error-prone PCR was used to introduce mutations to improve integration efficiency.
It enables efficient and specific integration of donor DNA into user-defined target sequences, reducing off-target events and improving the accuracy and efficiency of genome manipulation.
