ataxin 3(ATXN3) Homo sapiens 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.

disease:Defects in ATXN3 are the cause of spinocerebellar ataxia type 3 (SCA3) [MIM:109150]; also known as Machado-Joseph disease (MJD). Spinocerebellar ataxia is a clinically and genetically heterogeneous group of cerebellar disorders. Patients show progressive incoordination of gait and often poor coordination of hands, speech and eye movements, due to degeneration of the cerebellum with variable involvement of the brainstem and spinal cord. SCA3 belongs to the autosomal dominant cerebellar ataxias type I (ADCA I) which are characterized by cerebellar ataxia in combination with additional clinical features like optic atrophy, ophthalmoplegia, bulbar and extrapyramidal signs, peripheral neuropathy and dementia. The molecular defect in SCA3 is the a CAG repeat expansion in ATX3 coding region. Longer expansions result in earlier onset and more severe clinical manifestations of the disease.,function:Interacts with key regulators (CBP, p300 and PCAF) of transcription and represses transcription. Acts as a histone-binding protein that regulates transcription. Acts as a deubiquitinating enzyme.,polymorphism:The MJD1a allele carries a single nucleotide substitution in codon 349 generating a stop codon instead of a Tyr. In the Japanese population, the MJD1a allele seems to be significantly associated with Gln expansion.,polymorphism:The poly-Gln region of ATXN3 is highly polymorphic (14 to 41 repeats) in the normal population and is expanded to about 55-82 repeats in spinocerebellar ataxia 3 (SCA3) patients.,similarity:Contains 1 Josephin domain.,similarity:Contains 3 UIM (ubiquitin-interacting motif) repeats.,subcellular location:Predominantly nuclear, but not exclusively, inner nuclear matrix.,subunit:Interacts with DNA repair proteins RAD23A and RAD23B.,tissue specificity:Ubiquitous.,
