PEP-0823 can be used as a blocking peptide with polyclonal antibody PA5-20708.

Target Information

Bora (Protein aurora borealis) is a key activator of Aurora Related Protein Kinase A (ARK-1), a centrosome-associated serine/threonine kinase that regulates centrosome maturation, bipolar spindle assembly, and chromosome segregation during mitosis.
Bora is localized to the nucleus until mitosis is initiated, then translocates to the cytoplasm in a Cdc2-dependent manner. Activation of Cdc2 initiates the release of Bora into the cytoplasm where it can bind and activate ARK-1.
PLK1 (polo-like kinase-1) interacts with Bora to control the accessibility of its activation loop for phosphorylation and activation by ARK-1. Bora and ARK-1 cooperatively activate PLK1 and control mitotic entry.
Bora mutants result in multipolar spindles in mitosis identical to those observed when ARK-1 function is blocked. Thus, the ARK1-Bora-PLK1 regulatory circuit in mammalian cells elucidates a key mechanism in cell cycle regulation.
At least three isoforms of Bora are known to exist.
