CRISPR genome editing approaches theoretically enable researchers to define the function of each human gene in specific cell types, but challenges remain to efficiently perform genetic perturbations in relevant models. In this work, we develop a library cloning protocol that increases sgRNA uniformity and greatly reduces bias in existing genome-wide libraries. We demonstrate that our libraries can achieve equivalent or better statistical power compared to previously reported screens using an order of magnitude fewer cells. This improved cloning protocol enables genome-scale CRISPR screens in technically challenging cell models and screen formats.

BK virus is implicated in polyomavirus-associated nephropathy (PVAN) and hemorrhagic cystitis, particularly in kidney transplant recipients, affecting the functionality of the transplanted kidney and posing a risk of graft loss. Despite these challenges, specific antiviral drugs targeting BK virus remain elusive. Agnoprotein, a small, positively charged protein encoded by the BK virus late gene, functions in the assembly, maturation, and release of the virus.

The CRISPR-Cas9 system has frequently been used for genome editing in Streptomyces; however, cytotoxicity, caused by off-target cleavage, limits its application. In this study, we implement innovative modification to Cas9, strategically addressing challenges encountered during gene manipulation using Cas9 within strains possessing high GC content genome. The Cas9-BD, a modified Cas9 with the addition of polyaspartate to its N- and C-termini, is developed with decreased off-target binding and cytotoxicity compared with wild-type Cas9.
