Bub1 is an evolutionarily conserved mitotic checkpoint control protein that is present in diverse organisms including yeast and humans. Bub1 is a serine/threonine protein kinase and is required for recruitment of Mad1, Mad2, Bub3, and CENP-E to kinetochores (Sharp-Baker and Chen in J Cell Biol 153:1239-1250, 2001). The evolutionarily conserved amino acid region in the N-terminus has been called as the CD1 domain. To clarify the action mechanism of Bub1 in controlling check point signals, we initiated an NMR structure determination of the Bub1 CD1 domain. Here, we report the sequence-specific backbone resonance assignments of CD1 domain of human Bub1 (hBub1CD1).
