Anti-ATXN7 antibodies are used in the immunodetection of the protein ataxin 7. In humans, the canonical protein has a reported length of 892 amino acid residues and a mass of 95.5 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 3 different isoforms have been reported for this protein. A member of the Ataxin-7 protein family, ATXN7 is known to act as component of the STAGA transcription coactivator-HAT complex. Post-translational modifications have been described, including sumoylation and protein cleavage. Synonyms for this target antigen include OPCA3, SCA7, SGF73, Autosomal dominant cerebellar ataxia with retinal degeneration, SAGA associated factor 73 kDa homolog, and ADCAII. ATXN7 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of ATXN7 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
