| Gene Symbol: | ATXN1 |
| Gene ID: | 6310 |
| Uniprot ID: | ATX1_HUMAN |
| Immunogen Region: | 742-791 aa |
| Specificity: | Phospho-Ataxin-1 (S776) Polyclonal Antibody detects endogenous levels of Ataxin-1 protein only when phosphorylated at S776. |
| Immunogen: | The antiserum was produced against synthesized peptide derived from the human Ataxin 1 around the phosphorylation site of Ser776 at the amino acid range 742-791 |
| Post Translational Modifications | Ubiquitinated by UBE3A, leading to its degradation by the proteasome. The presence of expanded poly-Gln repeats in spinocerebellar ataxia 1 (SCA1) patients impairs ubiquitination and degradation, leading to accumulation of ATXN1 in neurons and subsequent toxicity. Phosphorylation at Ser-775 increases the pathogenicity of proteins with an expanded polyglutamine tract. Sumoylation is dependent on nuclear localization and phosphorylation at Ser-775. It is reduced in the presence of an expanded polyglutamine tract. |
| Function | Chromatin-binding factor that repress Notch signaling in the absence of Notch intracellular domain by acting as a CBF1 corepressor. Binds to the HEY promoter and might assist, along with NCOR2, RBPJ-mediated repression. Binds RNA in vitro. May be involved in RNA metabolism. In concert with CIC and ATXN1L, involved in brain development. |
