Anti-catenin delta 1 antibodies are used for the immunodetection of the protein encoded by the CTNND1 gene. In humans, the canonical protein has a reported length of 968 amino acid residues and a mass of 108.2 kDa. Its subcellular localization is in the cell membrane, nucleus, and cytoplasm. It is reported to be expressed in vascular endothelium. A member of the Beta-catenin protein family, it is a reported key regulator of cell-cell adhesion that associates with and regulates the cell adhesion properties of both C-, E- and N-cadherins, being critical for their surface stability. Post-translational modifications have been described, including phosphorylation. Other names for this target antigen include BCDS2 and CAS. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 160 citations in the literature describe the use of catenin delta 1 antibodies in research. Immunohistochemistry is a widely used application for these antibodies. Western Blot, Immunocytochemistry, and Immunofluorescence are also common applications.
