Protein attributes

Sequence length	398 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Essential for the control of the cell cycle at the G2/M (mitosis) transition.
Subunit structure	Interacts with the CDC2 protein kinase to form a serine/threonine kinase holoenzyme complex also known as maturation promoting factor (MPF). The cyclin subunit imparts substrate specificity to the complex.
Developmental stage	Accumulates steadily during G2 and is abruptly destroyed at mitosis.
Sequence similarities	Belongs to the cyclin family. Cyclin AB subfamily.
