Human Ataxin 2 (ATXN2) interaction partners

1. Interrupted CAG expansions in ATXN2 gene associated with TDP-43 (TAR DNA binding Protein 43) inclusions occur in case of frontotemporal lobar degeneration.

2. Study found that ATXN2 intermediate-length expansions (larger than 26 repeats) were associated with an increased risk for amyotrophic lateral sclerosis.

3. This study showed that Normal ATXN2 alleles influences on the age at onset in spinocerebellar ataxia type 2.

4. STAU1 is recruited to mutant ATXN2 aggregates in spinocerebellar ataxia type 2 fibroblasts.

5. Intermediate-length ATXN2 repeat expansions might be a risk factor in Korean patients with ALS.

6. A novel variant in ATXN2 was identified in a Chinese population that was linked to age of onset in Machado-Joseph disease.

7. Among correlations found, such as that between dystonia and CAG expansion. Of note was the association between cognitive decline and the variant G at mitochondrial polymorphism A10398G, a variant formerly related to earlier ages at onset in SCA2.

8. SCA2 should be considered as a cause of typical Parkinson's disease phenotype even in the absence of cerebellar ataxia

9. Este es el primer estudio que permite sugerir la asociacion del polimorfismo (CAG)n del gen ATXN2 con el desarrollo de DM tipo 2 pura en poblacion de escasos recursos. Los alelos normales largos del VNTR son factores que aumentan el riesgo para DM tipo 2 pura en la poblacion mexicana analizada.

10. Deleterious non synonymous single nucleotide polymorphisms in ATXN2 Gene is associated with protein instability and conformational changes resulting in spinocerebellar ataxia.

11. Intermediate expansions of the CAG repeat in ATXN2 are associated with amyotrophic lateral sclerosis. They are mostly associated with TDP-43 proteinopathy, but not with 1C2-positive polyglutamine inclusions.

12. The findings of this sstudy suggest that ATXN2 may modify the known PINK1 roles for mitochondrial quality control and autophagy during cell stress.

13. The conclusion pof this study , the transcriptome data do not exclude the role of ATXN2 mutated alleles in Parkinson disease but its decrease protein expression in both SCA2c and SCA2p patients suggest a potential involvement of this gene in Parkinson disease.

14. C9orf72 and ATXN2 repeat expansions cause ataxia, dementia, and parkinsonism in a Guyana family.

15. Intermediate length repeat expansions of CAG (polyQ) repeat in the ATXN2 gene have also been reported to increase the risk of developing ALS.

16. Intermediate ATXN2 trinucleotide repeat expansion in ALS does not predict age of onset but does predict disease risk.

17. While depletion of C9ORF72 only has a partial deleterious effect on neuron survival, it synergizes with the toxicity of Ataxin-2 carrying intermediate length of polyglutamine expansions to induce motor neuron dysfunction and neuronal cell death.

18. ATXN2-AS, a gene antisense to ATXN2 has a role in SCA2 and possibly ALS pathogenesis.

19. It is not a regulatory gene in Italian amyotrophic lateral sclerosis patients with C9ORF72 GGGGCC expansion.

20. Selective loss of Purkinje cells in the cerebellar vermis of amyotrophic lateral sclerosis cases with intermediate repeat expansions in the ATXN2 gene.

Mouse (Murine) Ataxin 2 (ATXN2) interaction partners

1. Atxn2(-/-) mice showed an unstable rhythmicity of locomotor activity, but the level of PER1 and PER2 IR in the SCN did not differ between genotypes.

2. Findings provide evidence that the physiological functions and protein interactions of ATXN2 are relevant for calcium-mediated excitation of Purkinje cells as well as for ATXN2-triggered neurotoxicity.

3. Results from global proteome and metabolome profiling of Atxn2-KO mouse liver and cerebellum indicates that ATXN2 modulates nutrition and basal metabolism.

4. work suggests that in Machado-Joseph disease, mutant ataxin-3 drives an abnormal reduction of ataxin-2 levels, which overactivates poly(A)-binding protein, increases translation of mutant ataxin-3 and other proteins and aggravates Machado-Joseph disease.

5. ATXN2 interacted selectively with RGS8 mRNA. This interaction was impaired when ATXN2 harbored an expanded polyglutamine. Mutant ATXN2 also reduced RGS8 expression in an in vitro coupled translation

6. The physiological role of ATXN2 subtly modifies the abundance of cellular translation factors as well as global translation.

7. FBXW8 and PARK2 are sequestrated into insolubility by ATXN2 PolyQ expansions, but only FBXW8 expression is dysregulated

8. In KO mice, ATXN2 deficiency alters steady-state levels of Grb2 and Src, but does not block Grb2-dependent Ras signaling.

9. our data support the concept that expanded ATXN2 undergoes progressive insolubility and affects PABPC1 by a toxic gain-of-function mechanism with tissue-specific effects, which may be partially alleviated by the induction of FBXW8.

10. Ataxin-2 is not essential in development or during adult survival in the mouse, but leads to adult-onset obesity.

11. In analyses up to the age of 6 months, the ataxin-2 deficient mouse showed abdominal obesity and hepatosteatosis and this was associated with reduced insulin receptor expression in liver and cerebellum.

12. These data implicate ataxin-2 to play a role in endocytic receptor cycling.

13. results suggest that Atxn2-deficiency results in a specific set of behavioral and cellular disturbances that include motor hyperactivity and abnormal fear-related behaviors, but intact hippocampal function
