尽管对翻译后修饰(PTM)的抗体的需求不断增加,但PTM的分子识别的根本困难阻碍了使用常规方法产生高功能性抗PTM抗体。最近,已经建立的用于生物制剂开发的蛋白质工程和设计的先进方法被应用于成功地产生高功能的抗PTM抗体。此外,抗PTM抗体的结构分析揭示了前所未有的结合模式,大大增加了抗原结合表面。这些特征加深了对PTM特异性识别机制的理解,这可能导致产生具有精确特异性和高亲和力的抗PTM抗体的更有效方法。
Despite increasing demands for antibodies to post-translational modifications (PTMs), fundamental difficulties in molecular recognition of PTMs hinder the generation of highly functional anti-PTM antibodies using conventional methods. Recently, advanced approaches in protein engineering and design that have been established for biologics development were applied to successfully generating highly functional anti-PTM antibodies. Furthermore, structural analyses of anti-PTM antibodies revealed unprecedented binding modes that substantially increased the antigen-binding surface. These features deepen the understanding of mechanisms underlying specific recognition of PTMs, which may lead to more effective approaches for generating anti-PTM antibodies with exquisite specificity and high affinity.
