Description_x000D_ General description_x000D_ Aurora B (AIRK2, AIR-2 kinase, AIM-1) is a serine/threonine kinase. Aurora B is evolutionally conserved from yeast to human. The Drosophila serine/threonine protein kinase Aurora and the S. cerevisiae IpI1 kinase are highly homologous to human Aurora B._x000D_ Specificity_x000D_ Anti-Aurora B recognizes human, mouse, and rat Aurora B/AIR-2 Kinase enzymes. Detection of the Aurora B band by immunoblotting is specifically inhibited with the immunizing peptide._x000D_ Immunogen_x000D_ synthetic peptide corresponding to amino acid residues 1-19 of human Aurora B with C-terminal added cysteine conjugated to KLH._x000D_ Application_x000D_ Anti-Aurora B antibody has been used in:_x000D_ • in immunoblotting_x000D_ • in immunoprecipitation_x000D_ • in immunofluorescence_x000D_ • in immunofluorescence staining_x000D_ • in western blotting_x000D_ Rabbit polyclonal anti-Aurora B antibody is used to tag Aurora B/AIR-2 Kinase for detection and quantitation by immunocytochemical and immunohistochemical (IHC) techniques. It is used as a probe to determine the presence and roles of Aurora B/AIR-2 Kinase in chromosome segregation, cytokinesis, and cancer development._x000D_ Target description_x000D_ Auroa B is a member of a family of Auora kinases that function for proper chromosomal segregation during mitosis. Auora B localizes specifically to the kinetochores of microtubules._x000D_ Physical form_x000D_ Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide._x000D_ Disclaimer_x000D_ Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals._x000D_ Biochem/physiol Actions_x000D_ Aurora B plays key roles in chromosome segregation, cytokinesis, and cancer development. It also plays a role in chromosomal condensation by phosphorylating the H3 histone. In C. elegans, Aurora-B is required for normal localization and function of the ZEN-4/CeMKLP (Kinesin like protein/mitotic kinesin-like protein), a kinesin-related protein essential for completion of cytokinesis. Loss of the Aurora B kinase results in chromosome segregation defects and failures in cytokinesis. Aurora B displays a localization pattern typical of chromosomal passenger proteins as the inner centromeric protein (INCENP), TD-60 and Survivin. INCENP and Survivin interact directly with Aurora B. Chromosomal passenger proteins undergo dynamic redistribution during mitosis. They localize at centromers during prometaphase and relocate to midzone microtubules and midbodies during anaphase and telophase. The mRNA and protein levels of Aurora B are induced during G2M and decrease rapidly after the end of mitosis. Levels of Aurora B are increased in several human cancer cell lines.
