Ataxin 1

Ataxin-1 is a is_associated_with::protein that in humans is encoded by the ATXN1 is_associated_with::gene.

Mutations in this gene have been linked to neuronal death in suffers of is_associated_with::spinocerebellar ataxia type 1, an inherited neurodegenerative disease characterized by a progressive loss of cerebellar neurons. Pathogenic ATXN1 contains an abnormally elongated stretch of the amino acid glutamine. This causes the protein to spontaneously misfold and form aggregates. It has been shown that other neuronal proteins can modulate the formation of Ataxin-1 aggregates and that this in turn may affect aggregate-induced toxicity.
