Anti-ataxin 1 like antibodies are used for the immunodetection of the protein encoded by the ATXN1L gene. In humans, the canonical protein has a reported length of 689 amino acid residues and a mass of 73.3 kDa. Its subcellular localization is in the nucleus. It is reported to be expressed in cerebellum and cerebral cortex. A member of the ATXN1 protein family, it is reported to be a chromatin-binding factor that repress Notch signaling in the absence of Notch intracellular domain by acting as a CBF1 corepressor. Other names for this target antigen include brother of ATXN1 and brother of ataxin-1. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. ELISA is a widely used application for the ataxin 1 like antibodies listed below. In addition, Western Blot is also a common application.
