CC   -!- FUNCTION: Essential for the control of the cell cycle at the G2/M
CC       (mitosis) transition. Interacts with the CDC2 protein kinase to form
CC       MPF. G2/M cyclins accumulate steadily during G2 and are abruptly
CC       destroyed at mitosis (By similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the cyclin family. Cyclin AB subfamily.
CC       {ECO:0000305}.
