Description
Ataxin-3 is a deubiquitinating enzyme that maintains proteostasis, regulates transcription, and is involved in cytoskeletal dynamics, myogenesis, and degradation of misfolded chaperone substrates. It trims long polyubiquitin chains and interacts with STUB1/CHIP to limit ubiquitin chain length, preventing further elongation. Ataxin-3 Protein, Human (His) is the recombinant human-derived Ataxin-3 protein, expressed by E. coli, with N-6*His labeled tag
