Anti-TWSG1 antibodies are used in the immunodetection of the protein twisted gastrulation BMP signaling modulator 1. In humans, the canonical protein has a reported length of 223 amino acid residues and a mass of 25 kDa. It has been described to be a secreted protein. Up to 2 different isoforms have been reported for this protein. A member of the Twisted gastrulation protein family, TWSG1 is suspected to be involved in dorsoventral axis formation. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include twisted gastrulation protein homolog 1 and twisted gastrulation homolog 1. TWSG1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some TWSG1 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.
