Anti-PYGO1 antibodies are used in the immunodetection of the protein pygopus family PHD finger 1. In humans, the canonical protein has a reported length of 419 amino acid residues and a mass of 45.1 kDa. Its subcellular localization is in the nucleus. Up to 2 different isoforms have been reported for this protein. PYGO1 is known to be involved in signal transduction through the Wnt pathway. Synonyms for this target antigen include pygopus homolog 1 and pygopus-like protein 1. PYGO1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some PYGO1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
