    STRUCTURE
    motifs/domains
  • three characteristic repeat motifs termed the WK, SPE, and FPE motifs, responsible for spindle and kinetochore localization, and essential for proper chromosome alignment
  • C-terminal region containing the zinc-finger domains negatively regulates chromosome alignment, and phosphorylation in the FPE region counteracts this regulation

  • ZNF828-depleted cells showed severe chromosome misalignment associated with the poor resistance of K-fibres to the tension exerted upon establishment of sister kinetochore bi-orientation (
