Anti-PKN2 antibodies are used in the immunodetection of the protein protein kinase N2. In humans, the canonical protein has a reported length of 984 amino acid residues and a mass of 112 kDa. Its subcellular localization is in the nucleus and cytoplasm. Alternative splicing is reported to yield 5 different isoforms for this protein. It is ubiquitously expressed across many tissue types. A member of the AGC Ser/Thr protein kinase protein family, it is known to be involved with the apoptotic pathway and cell adhesion. Post-translational modifications have been described, including protein cleavage and phosphorylation. Synonyms for this target antigen include PRK2, PRKCL2, PRO2042, Pak-2, STK7, serine/threonine-protein kinase N2, PKN gamma, and PAK2.
