RL   Submitted (OCT-2000) to the EMBL/GenBank/DDBJ databases.
CC   -!- FUNCTION: Essential for the control of the cell cycle at the G2/M
CC       (mitosis) transition. {ECO:0000250}.
CC   -!- SUBUNIT: Interacts with the CDK1 protein kinase to form a
CC       serine/threonine kinase holoenzyme complex also known as maturation
CC       promoting factor (MPF). The cyclin subunit imparts substrate
CC       specificity to the complex (By similarity). {ECO:0000250}.
CC   -!- DEVELOPMENTAL STAGE: Accumulates steadily during G2 and is abruptly
CC       destroyed at mitosis.
CC   -!- SIMILARITY: Belongs to the cyclin family. Cyclin AB subfamily.
CC       {ECO:0000305}.
