Ataxin 7 (ATXN7) is a protein of the SCA7 gene, which contains 892 amino acids with an expandable poly(Q) region close to the N-terminus.
The SCA7 gene produces Ataxin 7, a protein with 892 amino acids, including a long poly(Q) stretch at its beginning. This information is relevant to understanding the function of this protein in relation to the neurodegenerative disease, Spinocerebellar Ataxia type 7 (SCA7).
