Summary: Enables cysteine-type deubiquitinase activity and ubiquitin protein ligase binding activity. Involved in cellular response to misfolded protein; monoubiquitinated protein deubiquitination; and proteolysis involved in protein catabolic process. Acts upstream of or within several processes, including cellular response to heat; exploration behavior; and ubiquitin-dependent protein catabolic process. Located in mitochondrial matrix; mitochondrial membrane; and nuclear inclusion body. Is expressed in several structures, including alimentary system; brain; hemolymphoid system gland; musculature; and testis. Used to study Machado-Joseph disease. Human ortholog(s) of this gene implicated in Machado-Joseph disease and late onset Parkinson's disease. Orthologous to human ATXN3 (ataxin 3). [provided by Alliance of Genome Resources, Nov 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
