Overview
Ataxin-3 (ATXN3) is a deubiquitinating enzyme encoded by the ATXN3 gene. Pathogenic CAG repeat expansions cause Machado-Joseph disease (MJD), also known as [spinocerebellar](/diseases/spinocerebellar-ataxia) ataxia type 3 (SCA3). ATXN3 plays important roles in protein quality control, transcriptional regulation, and cellular stress responses[@atxn2024].
Gene and Protein
- Gene: ATXN3 (Ataxin-3)
- Chromosomal Location: 14q32.12
- Protein: 364 amino acids (normal), expanded in disease
- Molecular Weight: ~42 kDa
- Aliases: MJD1, SCA3 protein, Josephin domain-containing protein 1
Protein Domains
ATXN3 contains several functional domains[@atxn2024a]:
Josephin domain: N-terminal protease domain with deubiquitinating activity
Polyglutamine (polyQ) tract: Pathogenic expansion in MJD
UIMs ([Ubiquitin](/mechanisms/ubiquitin-proteasome-system)-interacting motifs): Multiple UIMs for ubiquitin bindingNormal Physiological Functions
Deubiquitinating Activity
ATXN3 is a Josephin family DUB with specificity for K63-linked and K48-linked polyubiquitin chains[@atxn2024b]:
- Removes ubiquitin chains from substrates
- Regulates proteasomal degradation
- Modulates autophagy
- Processes ubiquitin precursors
Protein Quality Control
ATXN3 participates in cellular protein homeostasis:
- Component of the ubiquitin-proteasome system
- Interacts with valosin-containing protein (VCP/p97)
- Facilitates aggregate clearance
- Protects against proteotoxic stress
Transcriptional Regulation
ATXN3 modulates gene expression through:
- Interaction with transcription factors
- Histone deacetylase activity
- Co-activator/co-repressor functions
- Epigenetic regulation
Pathogenic Mechanisms in MJD/SCA3
Polyglutamine Expansion
The CAG repeat expansion results in an expanded polyglutamine tract[@polyglutamine2024]:
- Normal: 12-44 CAG repeats
- Pathogenic: 52-86+ repeats
- Toxic gain-of-function
- Protein misfolding
Expanded ATXN3 forms aggregates:
- Intranuclear inclusions
- Ubiquitin-positive aggregates
- Sequestration of normal proteins
- Proteostasis disruption
Transcriptional Dysregulation
Pathogenic ATXN3 affects:
- Gene expression programs
- Neuronal survival genes
- Neuroprotective factors
