ADAMTS13（a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13），又称温韦伯氏因子裂合酶（von Willebrand factor-cleaving protease，VWFCP）是一种含锌的金属蛋白酶。ADAMTS13可以裂解一种称为温韦伯氏因子（英语：von Willebrand factor）（vWf）的大型凝血因子。为一种主要由肝脏星状细胞(stellate cell)制造的蛋白酶，少量由血管内皮细胞、血小板、肾脏足细胞及肾小管上皮细胞分泌^[6]，在人体与动物实验中皆发现受试者接受部分肝切除手术后，ADAMTS13的活性会下降至正常值的30~40%，可见肝脏对ADAMTS13的制造具有重要的贡献。本酵素存在于血液之中，降解vWf多聚体，以降低它们的活性^[7]。

遗传学

ADAMTS13基因存在于第九对染色体（9q34）上^[7]。

发现

自1982年时，人们就知道遗传性血栓性血小板减少性紫癜（英语：thrombotic thrombocytopenic purpura）（TTP，一种微血管病性溶血性贫血（英语：microangiopathic hemolytic anemia））患者的血浆中，存在异常巨大的温韦伯氏因子多聚体（ULVWF）^[7]。

1994年，发现在高剪力下时，有一种血浆金属酶会从vWF第1605位的酪氨酸及1606位的甲硫氨酸间切割。1996年，两个独立研究团队分别发现该酵素。自接下来的两年，同样的两个团队证明了vWF裂合酶与小血管的血小板血栓生成相关。此外他们还报导了在大部分非遗传性TTP患者身上，能发现对抗ADAMTS13的IgG 抗体^[7]。

蛋白质组学

ADAMTS家族（英语：ADAMTS）目前共已知有19种蛋白质，ADAMTS13属于其中一员，与其他金属蛋白酶族同样有一个14个相异的结构域组成的结构，包括金属蛋白酶(metalloprotease)、解整合素(disintegrin)、TSP1(first thrombospondin type 1 repeat)和间隔域(spacer domain) ，但ADAMTS13并不具备穿膜蛋白结构，因此其不存在细胞膜上，而是随着血液循环在大小血管内作用。该家族的蛋白质拥有蛋白酶结构域，可以水解蛋白质，邻近则有解聚素（英语：disintegrin）结构域，且含有多个血小板反应蛋白（英语：thrombospondin）结构域。ADAMTS13含有8个血小板反应蛋白结构域，且无输水穿膜段，所以该蛋白并非膜蛋白^[7]。

临床角色

ADAMTS13缺乏症最早发现于Upshaw Schulman Syndrome（英语：Upshaw Schulman Syndrome），为一种复发性遗传性血栓性血小板减少性紫癜（英语：thrombotic thrombocytopenic purpura）。当时学界认为该病属于一种自身免疫疾病，因为该疾病使用血浆置换及IgG抑制剂。在ADAMTS13发现后，研究人员发现这些自身抗体会对抗该蛋白上的抗原表位^[7]^[8]^[9]。ADAMTS13具有裂解温韦伯氏因子多聚体(UL-VWFM)并降低温韦伯氏因子活性的功能，能抑止血小板堆积于微血管形成血栓。^[10]由血管内皮细胞分泌的ADAMTS13，可能负责大部分新生温韦伯氏因子多聚体的裂解，以达到即刻性抑止血栓形成的作用。当ADAMTS13受到自身抗体的攻击而导致活性下降(小于正常活性10%)，即可能造成呈现巨分子状态的温韦伯氏因子(也就是温韦伯氏因子多聚体)沉积后黏附于血管内皮细胞表层，促使微小血管中血小板凝集，使血液中游离的血小板数量不足，同时血管中的纤维蛋白增加亦破坏红细胞结构，形成不正常型态的血细胞 (例如:裂细胞Schistocyte)与发生溶血现象，导致产生获得性血栓性血小板减少性紫斑症的临床症状。

   研究中發現ADAMTS13低下除了與獲得性血栓性血小板減少性紫斑症的形成密切相關外，在其他栓塞性微血管病變(thrombotic microangiopathy,TMA)中ADAMTS13有不同程度的下降^[11] ，在敗血症、惡性高血壓病患及自體免疫患者中也有發生相似的變化^[12]^[13] ，因此合理的推論ADAMTS13活性下降雖然不一定成為直接造成上述疾病的成因，但極有可能在這些病症中擔任促成因子的角色。
