Background
|
Ataxin-3, also known as Machado-Joseph Disease (MJD) Protein 1 and Spinocerebellar Ataxia Type 3, is a 364 amino acid (aa), ubiquitously expressed cytoplasmic and nuclear protein with a predicted molecular weight of 42 kDa. Ataxin-3 functions as a deubiquitinating enzyme. Human Ataxin-3 shares 87% and 86% aa sequence identity with mouse and rat Ataxin-3, respectively. Full-length Ataxin-3 contains an N-terminal Josephin domain, two Ubiquitin interacting motifs, and a variable C-terminus consisting of a polyglutamine stretch and tail. As a deubiquitinating enzyme, Ataxin-3 plays a critical role in affecting the ubiquitination status of proteins for quality control and other cellular pathways. In turn, the ubiquitination of Ataxin-3 is was shown to enhance its capacity to cleave Ubiquitin chains. By opposing the actions of the Ubiquitin-conjugating (E2) enzyme UBE2W, Ataxin-3 is believed to control the activity of the Ubiquitin ligase (E3) C-terminus of Hsp70 Interacting Protein (CHIP). CHIP binds to protein chaperones and represents an important molecular link between the chaperone and Ubiquitin-proteasome system. Expression of murine Ataxin-3 is thought to be important for myogenesis, an effect that is dependent on the regulation of Integrin alpha 5 levels. Mutations in the ATXN3 gene are the cause of MJD, also known as spinocerebellar ataxia 3, an autosomal dominant neurodegenerative disorder characterized by nuclear aggregation of Ataxin-3 molecules featuring an expanded polyglutamine tract.

保存条件：
Ataxin 3 Rabbit Polyclonal Antibody -20ºC保存，Western一抗稀释液-20ºC或4ºC保存，一年有效。Western一抗稀释液优先推荐4ºC保存，长期不使用可以考虑-20ºC保存，但冻融可能会导致出现轻微的浑浊和少量不溶物。
注意事项：
如果本抗体用于Western blot (WB)、免疫荧光(IF)、免疫细胞化学(ICC)等实验，请注意回收使用过的稀释抗体。回收的抗体通常至少可以重复使用5-10次。稀释后的抗体，包括已经使用过的稀释抗体，请4℃保存。
回收后重复使用的抗体，使用方法同新鲜稀释的抗体。如果在重复使用过程中发现抗体出现轻微混浊现象，可以10,000g离心1-3分钟，取上清用于后续检测。如果回收的抗体出现明显的絮状物或长霉长菌等情况，则可以考虑废弃该抗体。
提供的Western一抗稀释液也可以用于免疫荧光(IF)、免疫组化(IHC)、免疫细胞化学(ICC)等适当用途。如果希望获得最佳的检测效果，请考虑使用上述检测专用的一抗稀释液。
本产品仅限于专业人员的科学研究用，不得用于临床诊断或治疗，不得用于食品或药品，不得存放于普通住宅内。
