Prime editing, a cutting-edge CRISPR/Cas-based genome editing technique, has rapidly evolved with novel applications and improved versions, necessitating ongoing analysis and enhancement. This review explores the prime editing mechanism, optimization strategies, and the potential future of CRISPR/Cas9-associated genome editing. At the core of prime editing is a prime editor fusion protein, comprising a nickase and reverse transcriptase, and a prime editing guide RNA with essential components like a protospacer, scaffold, primer binding site, and reverse transcription template. Optimization efforts have focused on enhancing efficiency across different target organisms and compacting components for efficient viral delivery. Insights into prime editing mechanisms have led to improved efficiency through the recruitment of mismatch repair inhibitors. However, the evolution of prime editing requires the integration of new mechanisms, such as combining prime editors with integrases to enable precise editing and the insertion of large DNA fragments.
Key Points:
– Prime editing is a rapidly advancing CRISPR/Cas-based genome editing technique.
– Optimization efforts focus on enhancing efficiency and compacting components for viral delivery.
– Insights into prime editing mechanisms have led to improved efficiency through mismatch repair inhibitors.
