'''Cyclin B''' is a mitotic cyclin. The amount of cyclin B (which binds to [[Cdk1]]) and the activity of the cyclin B-Cdk complex rise through the cell cycle until mitosis, where they fall abruptly due to degradation. The complex of Cdk and cyclin B is called [[maturation promoting factor]] or Mitosis promoting factor (MPF).
