Aurora B also known as Aurora kinase B or AURKB is a serine/threonine protein kinase with a molecular mass of approximately 39 kDa. This protein expresses across various cell types and tissues playing a critical role during cell division. It localizes to the centromeres during early mitosis and later associates with the central spindle and midbody. Aurora B is a component of the chromosomal passenger complex (CPC) which includes other proteins such as INCENP survivin and borealin essential for its function.
Biological function summary
Aurora B kinase functions to ensure proper chromosome alignment segregation and cytokinesis during mitosis and meiosis. It phosphorylates various substrates to facilitate processes like correction of kinetochore-microtubule attachments and regulation of the mitotic checkpoint. As a part of the CPC Aurora B acts in coordination with other proteins to control these cellular events ensuring that cells divide accurately and safely.
Pathways
Aurora B integrates into the cell cycle and mitotic pathways operating closely with the spindle assembly checkpoint. It interacts with proteins like CENP-A and CENP-E ensuring error-free chromosome segregation. Aurora B's activity within these pathways is critical for maintaining genomic stability and preventing aneuploidy a condition linked to improper chromosome number.
Aurora B's malfunction associates with cancer and chromosomal instability. Overexpression or dysregulation of Aurora B kinase frequently occurs in several types of cancer contributing to tumorigenesis by promoting abnormal cell division. Proteins such as p53 a well-known tumor suppressor often become functionally compromised when Aurora B activity is altered further advancing disease progression. Aurora B also holds implications in other disorders marked by faulty cell cycle regulation emphasizing its potential as a therapeutic target.
