    • The invention provides methods and compositions for the rapid and sensitive detection of post-translationally modified proteins, and particularly of those with post-translational glycosylations. The methods can be used to detect O-GlcNAc posttranslational modifications on proteins on which such modifications were undetectable using other techniques. In one embodiment, the method exploits the ability of an engineered mutant of β-1,4-galactosyltransferase to selectively transfer an unnatural ketone functionality onto O-GlcNAc glycosylated proteins. Once transferred, the ketone moiety serves as a versatile handle for the attachment of biotin, thereby enabling detection of the modified protein. The approach permits the rapid visualization of proteins that are at the limits of detection using traditional methods. Further, the preferred embodiments can be used for detection of certain disease states, such as cancer, Alzheimer's disease, neurodegeneration, cardiovascular disease, and diabetes.
    • 本发明提供用于快速和灵敏检测翻译后修饰的蛋白质,特别是具有翻译后糖基化的蛋白质的方法和组合物。 该方法可用于检测蛋白质上的O-GlcNAc翻译后修饰,其中使用其它技术检测不到这些修饰。 在一个实施方案中,该方法利用了工程化突变体的-1,4'-半乳糖基转移酶选择性将非天然酮官能团转移到O-GlcNAc糖基化蛋白质上的能力。 一旦转移,酮部分用作生物素附着的通用手段,从而能够检测修饰的蛋白质。 该方法允许使用传统方法快速显示处于检测极限的蛋白质。 此外,优选的实施方案可用于检测某些疾病状态,例如癌症,阿尔茨海默病,神经变性,心血管疾病和糖尿病。
