Recombinant human Ataxin-3(Q22)/ATXN3 protein was determined by SDS-PAGE with Coomassie Blue.
Ataxin3 is a Machado-Josephine domain-containing deubiquitinating enzyme. Machado–Joseph disease (MJD) is a neurodegenerative disorder caused by polyQ expansion in ataxin-3. Ataxin3 is involved in protein homeostasis maintenance, transcription, cytoskeleton regulation, myogenesis and degradation of misfolded chaperone substrates.
