生物活性
TXN3 activity was validated using Ub-Rho110 as a substrate to assess its deubiquitinating function. The reaction rate showed a strong linear positive correlation with enzyme concentration (0–500 nM) over a 60-min reaction period.

Machado-Joseph disease, also known as spinocerebellar ataxia-3, is an autosomal dominant neurologic disorder. The protein encoded by this gene contains (CAG)n repeats in the coding region, and the expansion of these repeats from the normal 12-44 to 52-86 is one cause of Machado-Joseph disease. There is a negative correlation between the age of onset and CAG repeat numbers. Alternatively spliced transcript variants encoding different isoforms have been described for this gene.
