基因定点敲入技术是基因工程和基因治疗的核心工具，旨在避免传统随机整合方法的不可控性及异质性等问题，但是在实际的应用过程中却长期受编辑过程中的脱靶活性和低效性的限制。近年来，位点特异性重组酶系统(如Bxb1整合酶)和可编程核酸酶系统(如CRISPR/Cas9)的发展显著提升了基因敲入的精确性与效率。特别是Cas9-Bxb1整合酶系统的出现，实现了5~43 kb大片段DNA在基因组安全港(genomic safe harbor，GSH)位点的靶向整合，为疾病模型构建、基因功能研究和临床治疗提供了突破性平台。本文系统综述了位点特异性重组酶与核酸酶系统的研究进展，探讨了GSH的筛选策略及多组学数据在优化预测模型中的应用，并对比分析了twinPE+Bxb1与PASTE系统的优势与局限性。未来研究需聚焦于开发低脱靶活性的新型整合酶、优化无双链断裂(double strand break，DSB)编辑技术，以及建立跨物种GSH数据库，以进一步推动基因编辑技术在精准医学和合成生物学中的应用。

Gene-targeted knock-in technology serves as a cornerstone tool in genetic engineering and gene therapy, designed to circumvent the unpredictability and heterogeneityassociated with conventional random integration methods. However, its practical application has long been constrained by off-target activity and low efficiency during the editing process. Recent advances in site-specific recombinase systems (e.g., Bxb1 integrase) and programmable nuclease systems (e.g., CRISPR/Cas9) have significantly enhanced the precision and efficiency of gene knock-in. Notably, the Cas9-Bxb1 integrase system enables targeted integration of large DNA fragments (5−43 kb) into genomic safe harbor (GSH) sites, offering a transformative platform for disease modeling, functional genomics, and clinical therapeutics. This review systematically summarizes the progress of site-specific recombinase and nuclease systems, discusses GSH screening strategies and the role of multi-omics data in optimizing predictive models, and compares the strengths and limitations of twinPE+Bxb1 and PASTE systems. Future research should focus on developing novel integrases with low off-target activity, refining DSB-free editing technologies, and establishing cross-species GSH databases to advance applications in precision medicine and synthetic biology.
