We present 'significance analysis of interactome' (SAINT), a computational tool that assigns confidence scores to protein-protein interaction data generated using affinity purification-mass spectrometry (AP-MS). The method uses label-free quantitative data and constructs separate distributions for true and false interactions to derive the probability of a bona fide protein-protein interaction. We show that SAINT is applicable to data of different scales and protein connectivity and allows transparent analysis of AP-MS data.
我们提出了“互作组学分析”(SAINT),这是一种计算工具,用于为使用亲和纯化-质谱(AP-MS)生成的蛋白质-蛋白质相互作用数据分配置信分数。该方法使用无标记定量数据,并为真实和虚假相互作用构建单独的分布,以得出真实蛋白质-蛋白质相互作用的概率。我们表明,SAINT 适用于不同规模和蛋白质连通性的数据,并允许对 AP-MS 数据进行透明分析。
