- Sangamo published a medical research presentation outlining a platform to retarget large serine integrases for targeted gene integration at therapeutically relevant genomic sites.
- Work described retargeting Bxb1 integrase to TRAC locus, reaching about 29% targeted integration with up to 44% GFP expression in primary human T cells.
- Zinc finger fusions lifted on-target performance while maintaining a stronger specificity profile than activity-boosting mutations, which reduced specificity in genome-wide off-target assays.
- Synthetic donor engineering designed to remove need for wild-type Bxb1, with donor changes reported to eliminate top nominated off-target integration sites in K562 cells for most active TRAC reagents.
