Cyclin-dependent kinase control of the initiation-to-elongation switch of RNA polymerase II

Nature Structural &Molecular Biology, 2012
Promoter-proximal pausing by RNA polymerase II (Pol II) ensures gene-specific regulation and RNA quality control. Structural considerations suggested a requirement for initiation-factor eviction in elongation-factor engagement and pausing of ...

Cyclin-dependent kinases in C. elegans.

Cell division, 2006
Cell division is an inherent part of organismal development, and defects in this process can lead to developmental abnormalities as well as cancerous growth. In past decades, much of the basic cell-cycle machinery has been identified, and a major challenge in coming years will be to understand the complex interplay between cell division and ...

Matrix: a complex amalgam of structures and functions in tumor microenvironment

FEBS Open Bio, EarlyView.
The matrix is a dynamic, intricate three‐dimensional mesh of biomolecules with both structural and functional properties. This review deals with the complexity of this ‘molecular amalgam’ in the tumor microenvironment and highlights its importance in the maintenance and evolution of tumors by describing certain matrix biomolecules, such as ...

Inhibition of cyclin-dependent kinases by p21. [PDF]

Molecular Biology of the Cell, 1995
p21Cip1 is a cyclin-dependent kinase (Cdk) inhibitor that is transcriptionally activated by p53 in response to DNA damage. We have explored the interaction of p21 with the currently known Cdks. p21 effectively inhibits Cdk2, Cdk3, Cdk4, and Cdk6 kinases (Ki 0.5-15 nM) but is much less effective toward Cdc2/cyclin B (Ki approximately 400 nM) and Cdk5 ...

Liver‐specific lncRNAs associated with liver cancers

FEBS Open Bio, EarlyView.
Long non‐coding RNAs (lncRNAs) are regulatory molecules with various functions. They are more tissue‐specific than proteins and can be used as potential biomarkers, particularly in cancer diagnostics and prognosis. In this review, we have systematically compiled all lncRNAs with exclusive expression in the human liver, verified their liver specificity ...

Role for non-proteolytic control of M-phase-promoting factor activity at M-phase exit.

PLoS ONE, 2007
M-phase Promoting Factor (MPF; the cyclin B-cdk 1 complex) is activated at M-phase onset by removal of inhibitory phosphorylation of cdk1 at thr-14 and tyr-15. At M-phase exit, MPF is destroyed by ubiquitin-dependent cyclin proteolysis.

Cdk1 inactivation terminates mitotic checkpoint surveillance and stabilizes kinetochore attachments in anaphase [PDF]

, 2014
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].

Antibody‐Programmable Bimetallic Nanozymes for Transcriptional Blockade Therapy in HER2/ER‐Positive Breast Cancer

Advanced Functional Materials, EarlyView.
Zr‐Fe MOF@Ribociclib@Herceptin (ZFRH) efficiently targets/kills Human Epidermal Growth Factor Receptor 2/Estrogen Receptor‐positive (HER2/ER+) breast cancer cells. It combats tumors by: 1) Elevating ROS, altering redox balance; 2) Inhibiting transcription; 3) Inducing pyroptosis.

Cyclin C: The Story of a Non-Cycling Cyclin

Biology, 2019
The class I cyclin family is a well-studied group of structurally conserved proteins that interact with their associated cyclin-dependent kinases (Cdks) to regulate different stages of cell cycle progression depending on their oscillating expression ...
