Comments
Spinocerebellar ataxia type 7 protein, Ataxin-7, is seen both in the nucleus and cytoplasm in live cells and contains a highly conserved NES at amino acids 341-352. Mutation in the NES of polyglutamine expanded ataxin-7 increased toxicity in primary cerebellar neurons.

User Input
Accurate identification of NESs is difficult because many sequences in the genome match the NES consensus. Therefore, some published NESs may be mistakenly identified. Please help us improve the accuracy of NESdb by providing either a positive or negative flag for the NES in this entry. Supporting comments are required to process the flag.
