Description BUB1B spans 60 kb and is composed of 23 exons.

Protein

Note Protein name: BUBR1.
 
  Figure 2. Schematic representation of BUBR1 demonstrating significant functional or structural domains.
Description 1050 amino acids, 120 kDa.
Expression Ubiquituously expressed. Preferentially expressed in tissues with a high mitotic index.
Localisation Cytoplasmic in interphase cells. Bound to BUB3 or CENPE, it can be localised to nuclear kinetochores. BUBR1 also localises to centrosomes during interphase.
Function A central component of the mitotic spindle checkpoint that directly inhibits the anaphase-promoting complex/cyclosome until sister chromatids are correctly attached to the spindle, thus ensuring proper chromosome segregation during cell division. Also binds the motor protein CENPE, an interaction required for regulation of kinetochore-microtubule interactions and checkpoint signalling.
Homology BUBR1 is the mammalian homologue of yeast Mad3, a significant difference being that BUBR1 possesses a kinase domain which is absent in Mad3.

Mutations

Note Cells from BUB1B mutation-positive cases demonstrate an abnormal response to nocodazole-induced mitotic checkpoint activation.
 
  Figure 3. Schematic representation of BUB1B demonstrating the relative exon sizes and positions of known mutations. Truncating mutations are depicted above the figure, with missense mutations below. Biallelic mutations are represented by coloured lines, with mutations in the same individual in matching colours. Monoallelic mutations are represented by black lines and font.
Germinal Biallelic germline mutations have been found in eight MVA pedigrees (figure 3). Each family carries one missense mutation and one mutation that results in premature protein truncation or an absent transcript. Monoallelic truncating mutations have also been reported in several cases.

Note
  
Entity Mosaic variegated aneuploidy (MVA)
Note MVA is a rare recessive condition characterised by mosaic aneuploidies, predominantly trisomies and monosomies, involving multiple different chromosomes and tissues. Affected individuals typically present with severe intrauterine growth retardation and microcephaly. Eye anomalies, mild dysmorphism, variable developmental delay and a broad spectrum of additional congenital abnormalities and medical conditions may also occur.
Prognosis There is early mortality in a significant proportion of cases due to failure to thrive and/or complications of congenital abnormalities, epilepsy, infections or malignancy.
Cytogenetics The proportion of aneuploid cells varies but is usually >10% and is substantially greater than in normal individuals.
Oncogenesis The risk of malignancy in MVA is high, with Wilms tumour, rhabdomyosarcoma, leukaemia and granulosa cell tumour of the ovary reported in several cases. Myelodysplastic syndrome has also been observed. Three of the eight cases with biallelic BUB1B mutations developed a rhabdomyosarcoma and one individual developed a granulosa cell tumour of the ovary. Wilms tumour and rhabdomyosarcoma have been reported in monoallelic BUB1B cases.
  

To be noted

Biallelic mutations in CEP57 have also been identified in individuals with MVA syndrome.
