Comprehensive Summary

Currently, CRISPR/Cas9 technology has found widespread applications across various domains. However, the utility of CRISPR/Cas9 is encumbered by issues pertaining to its reliability and safety, primarily stemming from the uncontrolled activity of the system. Therefore, the design and development of CRISPR/Cas9 systems with controllable activity is of paramount importance. Biotin, characterized by its small molecular weight, and streptavidin, distinguished by its substantial spatial steric hindrance, can be harnessed as an ideal OFF switch (termed a "bioactivity brake") due to their interaction characteristics. In this work, we present a strategy that employs the streptavidin-biotin interaction as a "brake system" for CRISPR/Cas9, effectively allowing for the shutdown of the enzymatic activity of CRISPR/Cas9.image
