Ataxin-3抗体(A-7)是一种IgG2b κ小鼠单克隆Ataxin-3抗体(也称为Ataxin-3抗体),可通过WB、IP、IF、IHC(P)和ELISA检测小鼠、大鼠和人源的Ataxin-3蛋白。Ataxin-3抗体(A-7)既可以是非偶联的抗Ataxin-3抗体形式,也可以是多种偶联形式的抗Ataxin-3抗体,包括琼脂糖、HRP、PE、FITC和多种Alexa Fluor®偶联物。常染色体显性小脑性共济失调是一组由不稳定的CAG重复扩展编码多聚谷氨酰胺序列引起的神经退行性疾病。具有长多聚谷氨酰胺序列的蛋白质具有更强的聚集倾向,通常形成泛素化的核内包涵体。Machado-Joseph病(MJD)/脊髓小脑性共济失调3型(SCA3)基因编码ataxin-3,该基因含有一个多聚谷氨酰胺序列。在大多数神经元的病理条件下,ataxin-3被整合到大多数核内包涵体(NIs)中,并从其正常的细胞质定位中消失。然而,在SCA3的早期发病中,ataxin-3的病理形式与核基质的结合改变了ataxin-3的构象,从而暴露了多聚谷氨酰胺结构域。在正常脑组织中,野生型ataxin-3也可定位于泛素阳性的核内包涵体,即Marinesco体中,这是在神经元细胞受到某些应激条件(如衰老和多聚谷氨酰胺神经毒性)下发生的。稳定表达ataxin-3的细胞会上调炎症反应蛋白的mRNA水平,这表明炎症过程参与了脊髓小脑性共济失调3型的发病机制。Ataxin-3与酵母DNA修复蛋白RAD23的两个人类同源物HHR23A和HHR23B的N端结合,这对核苷酸切除修复非常重要。
