Origin licensing requires ATP binding and hydrolysis by the MCM replicative helicase.
(CELL PRESS, 2014-09-04)
Loading of the six related Minichromosome Maintenance (MCM) proteins as head-to-head double hexamers during DNA replication origin licensing is crucial for ensuring once-per-cell-cycle DNA replication in eukaryotic cells. ...
A Dynamical Framework for the All-or-None G1/S Transition.
(CELL PRESS, 2016-01-27)
The transition from G1 into DNA replication (S phase) is an emergent behavior resulting from dynamic and complex interactions between cyclin-dependent kinases (Cdks), Cdk inhibitors (CKIs), and the anaphase-promoting ...
Repression of Transcription at DNA Breaks Requires Cohesin throughout Interphase and Prevents Genome Instability.
(CELL PRESS, 2019-01-17)
Cohesin subunits are frequently mutated in cancer, but how they function as tumor suppressors is unknown. Cohesin mediates sister chromatid cohesion, but this is not always perturbed in cancer cells. Here, we identify a ...
PLK1 Activation in Late G2 Sets Up Commitment to Mitosis.
(CELL PRESS, 2017-06-06)
Commitment to mitosis must be tightly coordinated with DNA replication to preserve genome integrity. While we have previously established that the timely activation of CyclinB1-Cdk1 in late G2 triggers mitotic entry, the ...
Multiparametric Analysis of Cell Shape Demonstrates that β-PIX Directly Couples YAP Activation to Extracellular Matrix Adhesion.
(CELL PRESS, 2017-01-25)
Mechanical signals from the extracellular matrix (ECM) and cellular geometry regulate the nuclear translocation of transcriptional regulators such as Yes-associated protein (YAP). Elucidating how physical signals control ...
Cyclin B1 is essential for mitosis in mouse embryos, and its nuclear export sets the time for mitosis.
(ROCKEFELLER UNIV PRESS, 2018-01-02)
There is remarkable redundancy between the Cyclin-Cdk complexes that comprise the cell cycle machinery. None of the mammalian A-, D-, or E-type cyclins are required in development until implantation, and only Cdk1 is ...
TOPBP1 recruits TOP2A to ultra-fine anaphase bridges to aid in their resolution.
(NATURE PUBLISHING GROUP, 2015-03-12)
During mitosis, sister chromatids must be faithfully segregated to ensure that daughter cells receive one copy of each chromosome. However, following replication they often remain entangled. Topoisomerase IIα (TOP2A) has ...
Targeting Bromodomain and Extra-Terminal (BET) Family Proteins in Castration-Resistant Prostate Cancer (CRPC).
(AMER ASSOC CANCER RESEARCH, 2018-07-01)
Purpose: Persistent androgen receptor (AR) signaling drives castration-resistant prostate cancer (CRPC) and confers resistance to AR-targeting therapies. Novel therapeutic strategies to overcome this are urgently required. ...
