摘要： The invention provides methods, systems and reagents for regulating pH-sensitive protein interaction by incorporating non-natural amino acids into the protein (e.g. an antibody, or its functional fragment, derivative, etc.). The invention also relates to specific uses in regulating pH-sensitive binding of antibodies to tumor site, by conferring enhanced tumor-specificity/selectivity. In that embodiment, the non-natural amino acids preferably have desirable side-chain pKa's, such that at below physiological pH (e.g. about pH 6.3-6.5) the non-natural amino acid confer enhanced binding to tumor antigens in acidic environments. Such non-natural amino acids can be incorporated by any suitable means, such as by utilizing a modified aminoacyl-tRNA synthetase to charge the nonstandard amino acid to a modified tRNA, which forms strict Watson-Crick base-pairing with a codon that normally forms wobble base-pairing with natural tRNAs (e.g. the degenerate codon orthogonal system.
摘要翻译：本发明提供了通过将非天然氨基酸掺入蛋白质（例如抗体或其功能片段，衍生物等）来调节pH敏感蛋白质相互作用的方法，系统和试剂。本发明还涉及通过赋予增强的肿瘤特异性/选择性来调节抗体对肿瘤部位的pH敏感结合的具体用途。在该实施方案中，非天然氨基酸优选具有所需的侧链pKa，使得在低于生理pH（例如约pH 6.3-6.5）下，非天然氨基酸在酸性环境中赋予增强的与肿瘤抗原的结合。这样的非天然氨基酸可以通过任何合适的方式并入，例如通过利用修饰的氨酰-tRNA合成酶将非标准氨基酸装入修饰的tRNA，其与通常形成的密码子形成严格的沃森 - 克里克碱基配对与天然tRNA的摆动碱基配对（如简并密码子正交系统）。
