背景資料: Ataxin 3 is otherwise known as Machado-Joseph disease protein 1. Machado–Joseph disease is a hereditary autosomal dominant neurodegenerative disorder. ATXN3 contains trinucleotide CAG repeats in the coding region， and the expansion of these repeats from the normal 13-36 to 68-79 causes the Machado-Joseph disease. ATXN3 is a poly-ubiquitin-binding protein whose cellular turnover is regulated by its catalytic activity.
In addition， ATXN3 is a proteasome-associated factor which mediates the degradation of ubiquitinated proteins. ATXN3 folds reversibly using a single intermediate； partial destabilization of ATXN3 by chemical denaturation causes the formation of fibrillar aggregates by the non-pathological variant.
Ataxin-3 interacts with the major histone acetyltransferases cAMP-response-element binding protein （CREB）-binding protein， p300， and p300/CREB-binding protein-associated factor and hinders transcription by these coactivators.

溶解建議: Sterile filtered colorless solution. The ATXN3 protein solution contains 20mM Tris-HCl buffer （pH 7.5）， 2mM DTT， 50mM NaCl and 10% glycerol.

保存建議: Store at 4℃ if entire vial will be used within 2-4 weeks. Store， frozen at -20℃ for longer periods of time. For long term storage it is recommended to add a carrier protein （0.1% HSA or BSA）. Avoid multiple freeze-thaw cycles.

其他: ProSpec 是一家全球著名細(xì)胞因子蛋白生產(chǎn)和研發(fā)的公司，具有20多年的生產(chǎn)經(jīng)驗(yàn)，專注于蛋白（重組及合成）生產(chǎn)研發(fā)。我們的核心產(chǎn)品包括：干擾素、白介素、骨蛋白、腫瘤壞死因子、成纖維生長(zhǎng)因子、瘦素、干細(xì)胞因子、催乳素、表皮生長(zhǎng)因子、胰島素樣生長(zhǎng)因子、神經(jīng)生長(zhǎng)因子、集落刺激因子、激素、酶、病毒抗原以及各種重組蛋白等。領(lǐng)先的生產(chǎn)工藝和規(guī)模使其可以提供毫克到克級(jí)蛋白，價(jià)格優(yōu)于同類公司。絕大部分產(chǎn)品是天然成熟型蛋白，而不含有標(biāo)簽蛋白。考慮到大部分研究者希望能更靈活地配制蛋白溶液，ProSpec-Tany絕大部分產(chǎn)品沒(méi)有添加保護(hù)劑或鹽，這就對(duì)工藝提出了更高的要求。同時(shí)，ProSpec-Tany絕大部分產(chǎn)品為凍干粉，因此易于運(yùn)輸和保存。
