The kinetics of G2 and M transitions regulated by B cyclins. [PDF]
PLoS ONE, 2013 B cyclins regulate G2-M transition. Because human somatic cells continue to cycle after reduction of cyclin B1 (cycB1) or cyclin B2 (cycB2) by RNA interference (RNAi), and because cycB2 knockout mice are viable, the existence of two genes should be an ...

Cyclin B and Cyclin A Confer Different Substrate Recognition Properties on CDK2 [PDF]
Cell Cycle, 2007 The transitions of the cell cycle are regulated by the cyclin dependent protein kinases (CDKs). The cyclins activate their respective CDKs and confer substrate recognition properties. We report the structure of phospho-CDK2/cyclin B and show that cyclin B confers M phase-like properties on CDK2, the kinase that is usually associated with S phase ...

Phosphorylation of Ubc9 by Cdk1 enhances SUMOylation activity. [PDF]
PLoS ONE, 2012 Increasing evidence has pointed to an important role of SUMOylation in cell cycle regulation, especially for M phase. In the current studies, we have obtained evidence through in vitro studies that the master M phase regulator CDK1/cyclin B kinase ...

Cyclin D3 Governs Clonal Expansion of Dark Zone Germinal Center B Cells
Cell Reports, 2020 Summary: Germinal center (GC) B cells surge in their proliferative capacity, which poses a direct risk for B cell malignancies. G1- to S-phase transition is dependent on the expression and stability of D-type cyclins.

A data-driven, mathematical model of mammalian cell cycle regulation. [PDF]
PLoS ONE, 2014 Few of >150 published cell cycle modeling efforts use significant levels of data for tuning and validation. This reflects the difficultly to generate correlated quantitative data, and it points out a critical uncertainty in modeling efforts. To develop a

The Crystal Structure of Human Cyclin B [PDF]
Cell Cycle, 2007 Cyclin B is the key regulatory protein controlling mitosis in all eukaryotes, where it binds cyclin-dependent kinase, cdk1, forming a complex which initiates the mitotic program through phosphorylation of select proteins. Cyclin B regulates the activation, subcellular localization, and substrate specificity of cdk1, and destruction of cyclin B is ...

PP2A function toward mitotic kinases and substrates during [PDF]
BMB Reports, 2013 To maintain cellular homeostasis against the demands of theextracellular environment, a precise regulation of kinases andphosphatases is essential. In cell cycle regulation mechanisms,activation of the cyclin-dependent kinase (CDK1) and cyclin Bcomplex ...

Specialization and Targeting of B-Type Cyclins [PDF]
Molecular Cell, 1999 The B-type cyclins of S. cerevisiae are diversified with respect to time of expression during the cell cycle as well as biological function. We replaced the early-expressed CLB5 coding sequence with the late-expressed CLB2 coding sequence, at the CLB5 locus.

Genomic landscape of salivary gland tumors. [PDF]
, 2015 Effective treatment options for advanced salivary gland tumors are lacking. To better understand these tumors, we report their genomic landscape. We studied the molecular aberrations in 117 patients with salivary gland tumors that were, on physician ...
