ATXN10 (Ataxin-10) is a ubiquitously expressed protein encoded by the ATXN10 gene located on human chromosome 22q13.31. It plays critical roles in cellular processes, including apoptosis, cell cycle regulation, and microtubule dynamics. The protein contains multiple polyglutamine (polyQ)-like domains and a C-terminal leucine-rich repeat (LRR) domain, suggesting involvement in protein-protein interactions. In its physiological state, ATXN10 supports neuronal survival and cerebellar function, particularly in Purkinje cells.
Pathologically, ATXN10 is linked to spinocerebellar ataxia type 10 (SCA10), an autosomal dominant neurodegenerative disorder caused by an abnormal ATTCT pentanucleotide repeat expansion in intron 9 of the gene. This expansion leads to toxic RNA foci and/or the production of an expanded polyglutamine-containing protein isoform (via repeat-associated non-AUG translation), triggering neuronal dysfunction. SCA10 manifests as progressive motor coordination loss, seizures, and cerebellar atrophy.
Recombinant ATXN10 proteins are engineered using expression systems (e.g., E. coli, mammalian cells) to study its structure-function relationships and disease mechanisms. These purified proteins enable biochemical assays, crystallography studies, and drug screening. Researchers utilize them to investigate how mutant ATXN10 disrupts RNA processing, induces mitochondrial stress, or impairs ubiquitin-proteasome pathways. Additionally, recombinant forms serve as antigens for antibody development and tools to explore therapeutic strategies like antisense oligonucleotides or small molecule inhibitors targeting pathogenic pathways. Current challenges include elucidating the exact molecular triggers of neurodegeneration and optimizing ATXN10-targeted therapies for clinical translation.
