Biological function summary
CENP-B participates in the assembly of the centromere protein complex contributing to the stability and maintenance of the centromere structure during cell division. It acts as a foundation for kinetochore nucleation ensuring proper chromosome segregation. CENP-B is involved in the formation of the CENP-A nucleosome complex important for accurate chromosomal alignment and separation.
Pathways
CENP-B is essential in the mitotic spindle assembly and chromosome segregation pathways. This protein interacts with CENP-A a variant histone which integrates into centromeric nucleosomes to initiate the formation of functional kinetochores. Additionally CENP-B interacts with CENP-C facilitating the recruitment of other centromere-associated proteins needed for chromosome dynamics during mitosis.
