CD59，亦称为“膜攻击复合物（MAC）抑制蛋白”（MAC-inhibitory protein, MAC-IP）、“膜反应性溶血抑制物”（membrane inhibitor of reactive lysis, MIRL）、“膜攻击复合物抑制因子”（membrane attack complex inhibitory factor, MACIF）或保护素（protectin），在人体内是一种由CD59基因编码的糖蛋白，属于分化簇（Cluster of Differntiation, CD）的一种。CD59属于LY6/uPAR/α-神经毒素蛋白家族。 CD59通过糖化肌醇磷脂（GPI）基团锚定在细胞膜上。当补体系统激活并已产生C5b678复合物时，CD59会阻止补体成分C9聚集到上述复合体上，从而阻止膜攻击复合物（MAC）的形成。同时，细胞也会收到信号，通过胞吞作用摄入CD59-CD9复合物。

能影响GPI基团的突变会引起红细胞膜上的CD59分子和衰变加速因子（CD55）数量减少，可引发阵发性夜间血红素尿症。

部分病毒，例如HIV、巨细胞病毒、牛痘病毒能够通过将宿主细胞的CD59整合到自己的包膜上来逃避补体系统的攻击。
