13. Data indicate that in spinocerebellar ataxia type 1 patients the spinocerebellar ataxia type 1 protein trinucleotide repeat expansion (CAG)n was great than 39, comparing with normal 6-38.

14. This study reports the results of molecular dynamics simulations of AXH monomer of Ataxin-1.

15. Systematic replacement of each lysine residue in the AXH domain revealed that the lysine at 589 (K589) of ATXN1 is essential for its ubiquitylation by UbcH6.

16. Results show that two SNPs in ATXN1 gene have a founder effect of the same repeat carrying allele as in the general Indian population suggesting that that Spinocerebellar ataxia type 1 disease onset is significantly delayed when transmission is maternal.

17. this work provides the structural and molecular basis of the interaction between RBM17 and the phosphorylated form of ATXN1.

18. Partner recognition of the AXH domain of the transcriptional co-regulator ataxin-1 is fine-tuned by a subtle balance between self- and hetero-associations.

19. We measured cerebellar neurochemical alterations in a knock-in mouse model of spinocerebellar ataxia type 1, a hereditary movement disorder, using ultra-high field magnetic resonance spectroscopy (MRS).

20. Data indicate that the alternative ataxin-1 (ATXN1) protein is constitutively co-expressed and interacts with ATXN1.

Mouse (Murine) Ataxin 1 (ATXN1) interaction partners

1. expanded ATXN1 stimulates the proliferation of postnatal cerebellar stem cells in SCA1 mice. These hyperproliferating stem cells tended to differentiate into GABAergic inhibitory interneurons rather than astrocytes; this significantly increased the GABAergic inhibitory interneuron synaptic connections, disrupting cerebellar Purkinje cell function in a non-cell autonomous manner.

2. Reduction of protein kinase A-mediated ATXN1-pS776 results in enhanced degradation of ATXN1 and improved cerebellar-dependent motor performance.

3. Disruption of the ATXN1-CIC interaction shows that it is at the crux of cerebellar toxicity in spinocerebellar ataxia type 1.

4. we also found that brain-region-specific differences occur early in disease initiation and progression, and they are shared across the two mouse models of SCA1. This suggests different mechanisms of degeneration at work in the inferior olive and cerebellum

5. Furthermore, pharmacological inhibition of PAKs decreases ATXN1 levels in a mouse model of SCA1. To explore the potential of using PAK inhibitors in combination therapy, we combined the pharmacological inhibition of PAK with MSK1, a previously identified modulator of ATXN1, and examined their effects on ATXN1 levels. We found that inhibition of both pathways results in an additive decrease in ATXN1 levels.

6. Sca-1(+) cardiac fibroblasts direct the type of immune cells infiltrating the heart during cardiac inflammation and drive the development of heart failure.

7. Functional impairment of YAP/YAPdeltaC by mutant Atxn1 during development determines the adult pathology of spinocerebellar ataxia type 1 by suppressing RORalpha-mediated transcription.

8. data suggest GSK3b and mTOR pathways modulate this ATXN1 function in spinocerebellar ataxia type-1 (SCA1)pathogenesis that could be targeted therapeutically prior to the onset of disease symptoms in SCA1 and other pathologies involving dysregulation of ATXN1 functions.

9. Maternal diabetes induced caspase 3-dependent apoptosis in Sca1(+) cardiac progenitor cells derived from embryonic day 17.5 (E17.5). Both maternal diabetes and high glucose in vitro activated the pro-apoptotic transcription factor, Forkhead O 3a (FoxO3a) via dephosphorylation at threonine 32 (Thr-32) residue.

10. Data establish a novel role for ATXN1 in the hippocampus as an intrinsic regulator of precursor cell proliferation, and suggest a mechanism by which polyQ expansion and loss of ATXN1 affect hippocampal function, potentially contributing to cognitive deficits and depression
