描述：

XIAP Antibody能够检测内源水平XIAP总蛋白。该抗体不与其它凋亡抑制子发生交叉反应。该多克隆抗体是由合成的人源XIAP蛋白N末端相对应的肽段免疫动物而制备的。抗体由protein A和肽亲和层析技术纯化。

凋亡抑制因子蛋白(IAP) 家族包含一个进化上保守的凋亡抑制分支，此分支蛋白包含70个氨基酸BIR (杆状病毒抑制重复) 域(1,2)。在人类中，此家族的蛋白包含c-IAP1，c-IAP2，XIAP，survivin，livin 和NAIP。IAP 家族成员在癌细胞系和原癌中过表达，尤其是survivin和livin, 表明这些蛋白在癌症发展过程中起到了重要作用(3-5)。一般来讲，IAP蛋白是通过直接抑制几个caspases的活性发挥作用, 包括caspase-3、caspase-7和caspase-9 (5,6)。另外，IAP家族的成员与线粒体蛋白Smac的结合，阻止了它们与caspase-9的互作，因此引起了caspase的加工及其激活 (2)。

原厂资料：

Specificity / Sensitivity

XIAP Antibody detects endogenous levels of total XIAP protein. The antibody does not cross-react with other inhibitors of apoptosis.

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to the amino terminus of human XIAP. Antibodies are purified by protein A and peptide affinity chromatography.

Background

The inhibitor of apoptosis protein (IAP) family consists of an evolutionarily conserved group of apoptosis inhibitors containing a conserved 70 amino acid BIR (baculovirus inhibitor repeat) domain (1,2). Human members of this family include c-IAP1, c-IAP2, XIAP, survivin, livin, and NAIP. Overexpression of IAP family members, particularly survivin and livin, in cancer cell lines and primary tumors suggests an important role for these proteins in cancer progression (3-5). In general, the IAP proteins function through direct interactions to inhibit the activity of several caspases, including caspase-3, caspase-7, and caspase-9 (5,6). In addition, binding of IAP family members to the mitochondrial protein Smac blocks their interaction with caspase-9, thereby allowing the processing and activation of the caspase (2).
