Anti-catenin delta 2 antibodies are used for the immunodetection of the protein encoded by the CTNND2 gene. In humans, the canonical protein has a reported length of 1225 amino acid residues and a mass of 132.7 kDa. Its subcellular localization is in the nucleus. Alternative splicing is reported to yield 2 different isoforms for this protein. It is reported to be expressed in the brain; highest expression is observed in fetal brain. A member of the Beta-catenin protein family, it is known to have a critical role in neuronal development, particularly in the formation and/or maintenance of dendritic spines and synapses. Other names for this target antigen include NPRAP, T-cell delta-catenin, catenin (cadherin-associated protein), delta 2 (neural plakophilin-related arm-repeat protein), neurojungin, and GT24. Gene orthologs have been identified in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of catenin delta 2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
