描述：

IRAK1 (Human Specific) Antibody 能够检测内源性IRAK1蛋白总体水平。此抗体在生理条件下不与其它家族成员交叉反应。多克隆抗体是通过合成人源对应的IRAK1 gly696位点周围的肽段来免疫动物而获得。抗体是通过protein A和多肽亲和层析纯化。细胞白介素1(IL-1)受体相关激酶(IRAK)是丝氨酸/酪氨酸特异性激酶，它通过IL-1诱导的方式与IL-1受体发生共沉淀(1)。 哺乳动物的IRAK家族有四个成员(IRAK1, IRAK2, IRAK3/IRAK-M and IRAK4)。IL-1结合到IL-1的I类受体(IL-1RI)而促进形成包含IL-1RI, AcP, MyD88和IRAKs的复合体(2)。IRAK在IL-1刺激后能够在短时间内自磷酸化。接着IRAK从IL-1RI复合体上解离，泛素化并与两个膜结合蛋白 TAB2 和TRAF6结合。IRAK-TRAF6-TAB2复合体释放到细胞质中并激活蛋白激酶的级联反应，包括TAK1、IKKs 和应激活化激酶 (3)。

原厂资料：

Specificity / Sensitivity

IRAK1 (Human Specific) Antibody detects endogenous levels of total IRAK1 protein. No cross reactivity was detected with other family members at physiological conditions.

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding glycine 696 of human IRAK1. Antibodies are purified by protein A and peptide affinity chromatography.

Background

Interleukin-1 (IL-1) receptor-associated kinase (IRAK) is a serine/threonine-specific kinase that can be coprecipitated in an IL-1-inducible manner with the IL-1 receptor (1). The mammalian family of IRAK molecules contains four members (IRAK1, IRAK2, IRAK3/IRAK-M and IRAK4). The binding of IL-1 to IL-1 receptor type I (IL-1RI) initiates the formation of a complex that includes IL-1RI, AcP, MyD88 and IRAKs (2). IRAK undergoes autophosphorylation shortly after IL-1 stimulation. The subsequent events involve IRAK dissociation from the IL-1RI complex, its ubiquitination and its association with two membrane-bound proteins: TAB2 and TRAF6. The resulting IRAK-TRAF6-TAB2 complex is then released into the cytoplasm and activates protein kinase cascades, which include TAK1, IKKs and the stress-activated kinases (3).
