Biochem/physiol Actions

Ataxin3 (ATXN3) is a polyglutamine neurodegenerative disease protein involved in the ubiquitin-proteasome pathway. ATXN3 performs all the functions same as ubiquitin proteases such as, reducing polyubiquitylation of 125I-lysozyme by removing ubiquitin from polyubiquitin chains, cleaving a ubiquitin protease substrate and binding the specific ubiquitin protease inhibitor, ubiquitin-aldehyde. Mutation in the gene has been observed in spinocerebellar ataxia type 3 patients.

General description

Ataxin3 (ATXN3) is encoded by the gene mapped to human chromosome 14q32. The encoded protein is characterized with a ubiquitin interaction motif (UIM) domain involved in binding mono and/or polyubiquitylated proteins.
