    • The present invention provides methods for determining the level of protein activity in a cell by: (i) measuring abundances of cellular constituents in a cell in which the activity of a specific protein is to be determined so that a diagnostic profile is thus obtained; (ii) measuring abundances of cellular constituents that occur in a cell in response to perturbations in the activity of said protein to obtain response profiles and interpolating said response profiles to generate response curves; and (iii) determining a protein activity level at which the response profile extracted from the response curves best fits the measured diagnostic profile, according to some objective measure. In alternative embodiments, the present invention also provides methods for identifying individuals having genetic mutations or polymorphisms that disrupt protein activity, and methods for identifying drug activity in vivo by determining the activity levels of proteins which interact with said drugs.
    • 本发明提供了通过以下步骤确定细胞中蛋白质活性水平的方法:(i)测量要确定特定蛋白质的活性的细胞中细胞成分的丰度,从而获得诊断特征; (ii)测量在细胞中发生的细胞成分的丰度以响应所述蛋白质的活动中的扰动以获得反应谱并内插所述响应谱以产生响应曲线; 和(iii)根据一些客观的测定,确定从响应曲线提取的反应曲线最适合测量的诊断谱的蛋白质活性水平。 在替代实施方案中,本发明还提供了用于鉴定具有破坏蛋白质活性的遗传突变或多态性的个体的方法,以及通过测定与所述药物相互作用的蛋白质的活性水平来鉴定体内药物活性的方法。
