| Biochem/physiol Actions: | Unstable expansion of ataxin-2 (ATXN2) polyglutamine domain causes neurodegenerative diseases including spinocerebellar ataxia type-2, frontotemporal dementia and amyotrophic lateral sclerosis. Mode of action involves ATXN2 association with polyribosomes and poly(A) binding protein, thereby interfering with the translational regulation of particular mRNAs. Single nucleotide polymorphism in ATXN2 is associated with schizophrenia. ATXN2 is associated with the endocytosis complex and plays a role in endocytic receptor cycling. |

| Features and Benefits: | Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section. Every Prestige Antibody is tested in the following ways: • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues. • Protein array of 364 human recombinant protein fragments. |
| General description: | The gene ataxin-2 (ATXN2) is mapped to human chromosome 12q24.1. The protein belongs to ataxin-2 family. ATXN2 is present at the endoplasmic reticulum, plasma membrane and trans-Golgi network depending on the interacting partner. |
