Anti-AURKA antibodies are used in the immunodetection of the protein aurora kinase A. In humans, the canonical protein has a reported length of 403 amino acid residues and a mass of 45.8 kDa. Its subcellular localization is in the cytoplasm. It is reported to be highly expressed in the testis and weakly in skeletal muscle, thymus and spleen. A member of the Ser/Thr protein kinase protein family, AURKA is known to be involved with the apoptotic pathway and cell division. Post-translational modifications have been described, including ubiquitination and phosphorylation. Synonyms for this target antigen include ARK1, AURA, BTAK, PPP1R47, STK15, STK6, STK7, and AIK. AURKA gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Over 680 citations in the literature describe the use of AURKA antibodies in research. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
