General annotation (Comments)
| Function | Essential component of the mitotic checkpoint. Required for normal mitosis progression and tumor suppression. 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. Essential for tumor suppression. May play a role in regulating aging and fertility By similarity. Ref.4 Ref.5 |
| Catalytic activity | ATP + a protein = ADP + a phosphoprotein. |
| Enzyme regulation | Kinase activity stimulated by CENPE. Ref.3 |
| Subunit structure | Interacts with CENPE, CENPF, mitosin, PLK1 and BUB3. Part of a complex containing BUB3, CDC20 and BUB1B. Interacts with anaphase-promoting complex/cyclosome (APC/C). Interacts with CASC5 By similarity. Ref.3 |
| Subcellular location | Cytoplasm By similarity. Nucleus By similarity. Chromosome › centromere › kinetochore. Note: Cytoplasmic in interphase cells By similarity. Associates with the kinetochores in early prophase. Kinetochore localization requires BUB1, PLK1 and CASC5 By similarity. Ref.3 Ref.6 |
| Tissue specificity | Highly expressed in thymus followed by spleen. |
| Domain | The D-box targets the protein for rapid degradation by ubiquitin-dependent proteolysis during the transition from mitosis to interphase Potential. The BUB1 N-terminal domain directs kinetochore localization and binding to BUB3. |
| Post-translational modification | Proteolytically cleaved by caspase-3 in a cell cycle specific manner By similarity. The cleavage might be involved in the durability of the cell cycle delay By similarity. Acetylation at Lys-243 regulates its degradation and timing in anaphase entry By similarity. Ubiquitinated. Degraded by the proteasome By similarity. Sumoylated with SUMO2 and SUMO3. The sumoylation mediates the association with CENPE at the kinetochore By similarity. Autophosphorylated in vitro By similarity. Intramolecular autophosphorylation stimulated by CENPE By similarity. Phosphorylated during mitosis and hyperphosphorylated in mitotically arrested cells By similarity. Phosphorylation at Ser-659 and Ser-1033 occurs at kinetochores upon mitotic entry with dephosphorylation at the onset of anaphase By similarity. |
| Involvement in disease | Defects in Bub1b are involved in the development of lung and intestinal adenocarcinomas after exposure to a carcinogen. |
| Disruption phenotype | Mice die in utero. Ref.5 |
| Sequence similarities | Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. BUB1 subfamily. Contains 1 BUB1 N-terminal domain. Contains 1 protein kinase domain. |
