Centromere is the chromosomal region to which spindle microtubules attach in mitosis. Centromere protein A (CENP-A), a centromere-specific histone H3 variant , was originally identified by anti-centromere autoantibodies . Human CENP-A is assembled into prekinetochores in G1 phase, and is stably maintained through multiple cell divisions . We previously reported the relative position of three centromere auto antigens, CENP-A, CENP-B, and CENP-C, in human MDA435 cells in interphase nuclei and metaphase chromosomes . We then characterized the molecular behavior of CENP-A and heterochromatin protein 1α (HP1α) during mitosis in living MDA435 cells . Recently, Lidsky et al. reported the dynamics of Cid/CENP-A, CENP-C, and Cal 1 in Drosophila S2R+ cells, and presented the live-cell images stably expressing the Cid-EGFP and mCherry-PCNA through the cell cycle . However, the localization of mammalian CENP-A throughout the cell cycle in living cells is unclear.
