Reversal of terminal differentiation and control of DNA replication [PDF]
DNA replication in mammalian cells occurs in discrete nuclear foci. Here we show that terminally differentiated myotubes can be induced to reenter S phase and show the same pattern of replication foci as cycling cells.

Reactivation of the mitosis-promoting factor in postmitotic cardiomyocytes [PDF]
Cardiomyocytes cease to divide shortly after birth and an irreversible cell cycle arrest is evident accompanied by the downregulation of cyclin-dependent kinase activities.

Cell cycle regulation and anticancer drug discovery
Cellular growth, development, and differentiation are tightly controlled by a conserved biological mechanism: the cell cycle. This cycle is primarily regulated by cyclin-dependent kinase (CDK)-cyclin complexes, checkpoint kinases, and CDK inhibitors ...

Dynamic anticipation by Cdk2/Cyclin A-bound p27 mediates signal integration in cell cycle regulation [PDF]
p27$^{Kip1}$ (p27) is an intrinsically disordered protein (IDP) that folds upon binding to cyclin-dependent kinase (Cdk)$/$cyclin complexes (e.g., Cdk2$/$cyclin A), inhibiting their catalytic activity and causing cell cycle arrest. However, cell division progresses when stably Cdk2$/$cyclin A-bound p27 is phosphorylated on one or two structurally ...

Cell-cell contact and TGF-beta can arrest the cell cycle in G1. Mv1Lu mink epithelial cells arrested by either mechanism are incapable of assembling active complexes containing the G1 cyclin, cyclin E, and its catalytic subunit, Cdk2.

Cdk1 inactivation terminates mitotic checkpoint surveillance and stabilizes kinetochore attachments in anaphase [PDF]
Two mechanisms safeguard the bipolar attachment of chromosomes in mitosis. A correction mechanism destabilizes erroneous attachments that do not generate tension across sister kinetochores [1].

Novel structural features of CDK inhibition revealed by an ab initio computational method combined with dynamic simulations [PDF]
The rational development of specific inhibitors for the ~500 protein kinases encoded in the human genome is impeded by a poor understanding of the structural basis for the activity and selectivity of small molecules that compete for ATP binding. Combining classical dynamic simulations with a novel ab initio computational approach linear-scalable to ...

D type cyclins belong to a family of related proteins that bind to and activate several protein kinases named cyclin-dependent kinases (CDKs), which are involved in regulation of the cell division cycle.

Effect of cyclins and Cdks on the cyclin B1 promoter activation [PDF]
AbstractTo study the effect of several cyclins on cyclin B1 promoter activation, we co‐transfected cyclin A, cyclin E and cyclin D1 expressing plasmids with a cyclin B1 promoter construction driving a luciferase repotnter gene into NIH 3T3 cells. All three cyclins produced activation of the reporter gene, however, co‐transfection of cyclin A with a ...

Biological functions of CDK5 and potential CDK5 targeted clinical treatments. [PDF]
Cyclin dependent kinases are proline-directed serine/threonine protein kinases that are traditionally activated upon association with a regulatory subunit.
