The stages, pictured to the left, are G1-S-G2-M. The G1 stage stands for "GAP 1". MPF (Maturation Promoting Factor) includes the CdK and cyclins that triggers

Furthermore, G 2 cells enter mitosis prematurely if injected with active Cdk2–cyclin A complexes just completing S phase.

By contrast, cyclin-CDK complexes are inhibited by phosphorylation in adjacent threonine and tyrosine residues by the dual-specificity protein kinases, WEE1 and MYT1.

This interaction leads to phospho-adaptor Cks1-mediated inhibition of M-CDK to facilitate Cdc6 accumulation and sequestration in mitosis. The LxF motif and Cks1 also mediate the mutual inhibition between M-CDK and the tyrosine kinase Swe1. Se hela listan på de.wikipedia.org サイクリン依存性キナーゼ（サイクリンいぞんせいキナーゼ、英: cyclin-dependent kinase 、略称: CDK）はプロテインキナーゼのファミリーの1つであり、細胞周期を調節する役割が最初に発見された。 CDK1-cyclin B (Cyclin Dependent Kinase 1), also known as Cdc2-cyclin B (Cell division control protein kinase 2) or M-phase promoting factor (MPF), is a member of cyclin-dependent kinases implicated in cell cycle control in eukaryotes. Activation of the CDK1-cyclin B brings the onset of mitosis and is tightly regulated. 2019-07-11 · The unified model does not conflict with the single mitotic cyclin system because M-CDK, although it has the strongest intrinsic activity on the active-site level (Loog and Morgan, 2005, Kõivomägi et al., 2011b), can maintain robust ordering of the switches (Örd and Loog, 2019).

p53, a cell cycle regulator, leads to increased p21 expression. The eukaryotic cell cycle is regulated by the temporal activation of different cyclin-dependent kinase (CDK)/cyclin complexes. Whilst the level of the catalytic subunit of the complex, the CDK, remains relatively constant through the cycle, the level of the cyclin subunit generally oscillates.

S cyclin kan aktivera S-Cdk. I slutet av G2 fasen ökar nivåerna av M-cyclin och vi får ett M-Cdk komplex.
