BubR1 also known as BUB1B is an important protein in the mitotic checkpoint complex with an approximate mass of 120 kDa. BubR1 ensures proper chromosome alignment and segregation during cell division by inhibiting the anaphase-promoting complex/cyclosome (APC/C) until all chromosomes achieve proper attachment to the spindle. This protein localizes mainly to the kinetochores of chromosomes and is commonly expressed in dividing cells throughout the body.

Biological function summary

The spindle assembly checkpoint mechanism involves a complex in which BubR1 plays a central role. BubR1 along with other checkpoint proteins such as Bub1 and Mad2 forms a surveillance complex ensuring the correct attachment of microtubules to kinetochores. This action prevents premature progression to anaphase reducing the risk of aneuploidy and maintaining genomic stability.

Pathways

Mitotic checkpoint control critically involves BubR1 linking closely with several proteins including Mad2 and Cdc20. BubR1 integrates into the spindle checkpoint pathway a central player in regulating mitosis. Within this pathway BubR1 inhibits APC/CCdc20 activity preventing premature anaphase onset until all chromosomes are correctly oriented to divide. Interactions between these proteins ensure accurate mitotic progression and cellular replication fidelity.

BubR1 function directly impacts cancer development and premature aging syndromes. Defective BubR1 activity can lead to chromosomal instability a characteristic of many cancers including colorectal cancer. Moreover reduced BubR1 expression links with premature aging syndromes such as mosaic variegated aneuploidy through its interaction with proteins such as p53 highlighting its role in genome integrity maintenance and cellular aging processes.

Target data

Essential component of the mitotic checkpoint. Required for normal mitosis progression. The mitotic checkpoint delays anaphase until all chromosomes are properly attached to the mitotic spindle. One of its checkpoint functions is to inhibit the activity of the anaphase-promoting complex/cyclosome (APC/C) by blocking the binding of CDC20 to APC/C, independently of its kinase activity. The other is to monitor kinetochore activities that depend on the kinetochore motor CENPE. Required for kinetochore localization of CENPE. Negatively regulates PLK1 activity in interphase cells and suppresses centrosome amplification. Also implicated in triggering apoptosis in polyploid cells that exit aberrantly from mitotic arrest. May play a role for tumor suppression.
