Function

Deubiquitinating enzyme involved in protein homeostasis maintenance, transcription, cytoskeleton regulation, myogenesis and degradation of misfolded chaperone substrates (PubMed:12297501, PubMed:16118278, PubMed:17696782, PubMed:23625928, PubMed:28445460, PubMed:33157014). Binds long polyubiquitin chains and trims them, while it has weak or no activity against chains of 4 or less ubiquitins (PubMed:17696782). Involved in degradation of misfolded chaperone substrates via its interaction with STUB1/CHIP: recruited to monoubiquitinated STUB1/CHIP, and restricts the length of ubiquitin chain attached to STUB1/CHIP substrates and preventing further chain extension (By similarity). Interacts with key regulators of transcription and represses transcription: acts as a histone-binding protein that regulates transcription (PubMed:12297501). Acts as a negative regulator of mTORC1 signaling in response to amino acid deprivation by mediating deubiquitination of RHEB, thereby promoting RHEB inactivation by the TSC-TBC complex (PubMed:33157014). Regulates autophagy via the deubiquitination of 'Lys-402' of BECN1 leading to the stabilization of BECN1 (PubMed:28445460).

Activity summary

Ataxin 3 also known as ATXN3 is a protein that functions as a deubiquitinating enzyme. It plays an important role in protein homeostasis by editing ubiquitin chains on proteins marked for degradation. This protein is approximately 42 kDa in size and is expressed in various human tissues with higher expressions in the brain and testis. Ataxin 3 contains a polyglutamine (polyQ) tract which is responsible for its aggregation in certain pathologies.

Biological function summary

At the molecular level Ataxin 3 helps in regulating protein quality control by associating with the proteasome complex. It acts as a link between ubiquitination and protein degradation pathways. The involvement of Ataxin 3 in transcriptional regulation and cytoskeletal organization further highlights its importance in cellular health. Its deubiquitinating activity implies its participation in recycling ubiquitins which are important to maintaining ubiquitin pools within the cell.

Pathways

Ataxin 3 is embedded within the ubiquitin-proteasome system which is essential for protein degradation. It links with pathways such as the protein quality control and endocytosis pathways. Ataxin 3 interacts with proteins like parkin and Ubiquitin C-terminal hydrolase L1 (UCH-L1) both of which are important for removing damaged or misfolded proteins and in the prevention of protein accumulation. These interactions show its broad role in cell maintenance and preventing toxic accumulations.

Associated diseases and disorders

The malfunction of Ataxin 3 directly relates to Spinocerebellar Ataxia Type 3 (SCA3) also known as Machado-Joseph Disease. The elongated polyQ tract within Ataxin 3 leads to its aggregation resulting in neuronal death. This aggregation process is shared with proteins such as Ataxin 2 which also forms aggregates in certain neurological conditions indicating a pathogenic overlap with related neurodegenerative diseases. Understanding Ataxin 3’s role offers insights into therapeutic targets for these conditions.
