The family of mammalian E-type cyclins is composed of two proteins, termed cyclin E1 and E2. These two cyclins are widely expressed in proliferating cells. E-cyclins bind and activate cyclin dependent kinase CDK2. Cyclin E-CDK2 complexes were believed to play critical function in driving cell cycle progression of normal, nontransformed cells and of cancer cells. Several recent reports challenge this notion.

UI	MeSH Term	Description	Entries
D002453	Cell Cycle	The complex series of phenomena, occurring between the end of one CELL DIVISION and the end of the next, by which cellular material is duplicated and then divided between two daughter cells. The cell cycle includes INTERPHASE, which includes G0 PHASE; G1 PHASE; S PHASE; and G2 PHASE, and CELL DIVISION PHASE.

D004622	Embryo, Mammalian	The entity of a developing mammal (MAMMALS), generally from the cleavage of a ZYGOTE to the end of embryonic differentiation of basic structures. For the human embryo, this represents the first two months of intrauterine development preceding the stages of the FETUS.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D017353	Gene Deletion	A genetic rearrangement through loss of segments of DNA or RNA, bringing sequences which are normally separated into close proximity. This deletion may be detected using cytogenetic techniques and can also be inferred from the phenotype, indicating a deletion at one specific locus.	Deletion, Gene,Deletions, Gene,Gene Deletions
D042846	CDC2-CDC28 Kinases	A family of cell cycle-dependent kinases that are related in structure to CDC28 PROTEIN KINASE, S CEREVISIAE and the CDC2 PROTEIN KINASE found in mammalian species.

D051357	Cyclin-Dependent Kinase 2	A key regulator of CELL CYCLE progression. It partners with CYCLIN E to regulate entry into S PHASE and also interacts with CYCLIN A to phosphorylate RETINOBLASTOMA PROTEIN. Its activity is inhibited by CYCLIN-DEPENDENT KINASE INHIBITOR P27 and CYCLIN-DEPENDENT KINASE INHIBITOR P21.

D019927	Cyclin E	A 50-kDa protein that complexes with CYCLIN-DEPENDENT KINASE 2 in the late G1 phase of the cell cycle.
