| 產(chǎn)品介紹 | Alpha 1-Antichymotrypsin, a member of the serine proteinase inhibitor (serpin) family, inhibits neutrophil proteinase cathepsin G and mast cell chymases, and protects the lower respiratory tract from damage by proteolytic enzymes. It contains a reactive centre loop, which interacts with cognate proteinases, resulting in loop cleavage and a major conformational change. Recently, alpha 1-antichymotrypsin has been identified as a major constituent of the neurofibrillary plaques associated with Alzheimers disease, and in vitro studies have shown that it enhances the rate of amyloid-fibril formation. These observations and recent genetic evidence suggest that alpha 1-antichymotrypsin is important in the pathogenesis of Alzheimers disease. Function: Although its physiological function is unclear, it can inhibit neutrophil cathepsin G and mast cell chymase, both of which can convert angiotensin-1 to the active angiotensin-2. Subunit: Interacts with DNAJC1. Subcellular Location: Secreted. Tissue Specificity: Plasma. Synthesized in the liver. Like the related alpha-1-antitrypsin, its concentration increases in the acute phase of inflammation or infection. Found in the amyloid plaques from the hippocampus of Alzheimer disease brains. Similarity: Belongs to the serpin family.

AACT是由神經(jīng)膠質(zhì)細(xì)胞分泌并參與淀粉樣纖維生成和沉積的一種色氨酸蛋白酶抑制劑,被認(rèn)為是Aβ肽的假性底物，與Aβ肽具有很高的親合性，可促進(jìn)Aβ肽的纖維化以生成淀粉樣沉積。 ApoE作為AD的另一種病理伴隨性物質(zhì)，也可識別并與Aβ肽相結(jié)合，促進(jìn)Aβ肽沉積生成淀粉樣老年斑塊。由于AACT和ApoE在AD發(fā)病中具有共同的作用途徑，因此探討其相互作用可能是AD治療中一個(gè)新的途徑。 AACT是一種絲氨酸蛋白酶抑制劑，可以中和糜蛋白酶等酶活性的蛋白酶，存在于大多數(shù)的組織細(xì)胞、巨噬細(xì)胞以及多種胃腸道和肺部腫瘤中，但多形核白細(xì)胞中無此物質(zhì)，它可以作為組織細(xì)胞瘤和良性/惡性纖維組織細(xì)胞瘤的標(biāo)志。此抗體與人的AACT反應(yīng)，主要用于惡性纖維組織細(xì)胞瘤等惡性腫瘤的診斷,也可用于胃癌﹑肺癌、腎癌等腫瘤的研究。 |
