Amino acids in a region of ataxin-1 outside of the polyglutamine tract influence the course of disease in SCA1 transgenic mice.

Abstract excerpt

Spinocerebellar ataxia type 1 (SCA1) belongs to a family of polyglutamine induced neurodegenerative disorders. Transgenic mice that overexpress a mutant allele of the SCA1 gene develop a progressive ataxia and Purkinje cell pathology. In this report, the pathological importance of a segment of ataxin-1 previously shown to be important for protein-protein interactions was examined. While the absence of a 122 amino...
