Anti-CDC42BPA antibodies are used in the immunodetection of the protein CDC42 binding protein kinase alpha. In humans, the canonical protein has a reported length of 1732 amino acid residues and a mass of 197.3 kDa. Its subcellular localization is in the cytoplasm. Up to 6 different isoforms have been reported for this protein. It is notably expressed in the heart, brain, skeletal muscle, kidney, and pancreas, with little or no expression in the lung and liver. A member of the AGC Ser/Thr protein kinase protein family, CDC42BPA is reported to be a serine/threonine-protein kinase, which is an important downstream effector of CDC42 and plays a role in the regulation of cytoskeleton reorganization and cell migration. Synonyms for this target antigen include MRCKA, PK428, serine/threonine-protein kinase MRCK alpha, CDC42 binding protein kinase alpha (DMPK-like), and MRCK. CDC42BPA gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some CDC42BPA antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
