Eukaryota › Metazoa › Chordata › Craniata › Vertebrata › Euteleostomi › Mammalia › Eutheria › Euarchontoglires › Primates › Haplorrhini › Catarrhini › Hominidae › Homo

Protein attributes

Sequence length	432 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Essential for the control of the cell cycle at the G1/S (start) and the G2/M (mitosis) transitions.
Subunit structure	Interacts with the CDK2 and CDC2 protein kinases to form a serine/threonine kinase holoenzyme complex. The cyclin subunit imparts substrate specificity to the complex. When associated with CDK2 (but not with CDC2), interacts with SCAPER. Ref.9
Subcellular location	Nucleus. Cytoplasm. Note: Cytoplasmic when associated with SCAPER. Ref.9
Developmental stage	Accumulates steadily during G2 and is abruptly destroyed at mitosis.
Sequence similarities	Belongs to the cyclin family. Cyclin AB subfamily.
