Anti-PKN1 antibodies are used in the immunodetection of the protein protein kinase N1. In humans, the canonical protein has a reported length of 942 amino acid residues and a mass of 103.9 kDa. Its subcellular localization is in the cell membrane, nucleus, and cytoplasm. Up to 3 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the AGC Ser/Thr protein kinase protein family, PKN1 is known to be involved with the apoptotic pathway and chromatin organization. Synonyms for this target antigen include PAK-1, PAK1, PKN, PKN-ALPHA, PRK1, PRKCL1, serine/threonine-protein kinase N1, and DBK. PKN1 gene orthologs have been reported in the mouse, rat, bovine, zebrafish and chimpanzee species. A number of PKN1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
