Anti-protein kinase N3 antibodies are used for the immunodetection of the protein encoded by the PKN3 gene. In humans, the canonical protein has a reported length of 889 amino acid residues and a mass of 99.4 kDa. Its subcellular localization is in the nucleus and cytoplasm. It is reported to be expressed in prostate tumors and various cancer cell lines. A member of the AGC Ser/Thr protein kinase protein family, it is known to be involved with intracellular signal transduction and peptidyl-serine phosphorylation. Post-translational modifications have been described, including phosphorylation. Other names for this target antigen include serine/threonine-protein kinase N3, protein kinase PKN-beta, protein-kinase C-related kinase 3, and UTDP4-1. Gene orthologs have been identified in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some protein kinase N3 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
