Target Binding of Black Phosphorus Nanomaterial to Polo‐Like Kinase 1 for Cancer Chemotherapy: A Mutual Selection of Nanomaterial and Protein

Exploration, EarlyView.
This study investigates the effect of protein properties on the nanomaterial‐protein interaction and elucidates the molecular mechanisms underlying the targeted inhibition of polo‐like kinase (PLK1) by black phosphorus nanomaterials (BPNMs). The specific targeting inhibition is attributed to the intrinsic properties of both the PLK1 protein and the ...

Purification and Assay of the Budding Yeast Anaphase‐Promoting Complex [PDF]

, 2005
The anaphase-promoting complex (APC) is a central regulator of the eukaryotic cell cycle and functions as an E3 ubiquitin protein ligase to catalyze the ubiquitination of a number of cell cycle regulatory proteins. The APC contains at least 13 subunits in addition to two activator subunits, Cdc20 and Cdh1, that associate with the APC in a cell cycle ...

Targeting APC/CCDC20 by Pro-TAME Suppresses Tumor Proliferation and Induces Apoptosis in Endometrial Carcinoma

Clinical and Experimental Obstetrics & Gynecology
Background: Anaphase-promoting complex/cyclosome (APC/C) is a multi-subunit E3 ubiquitin ligase that recruits substrates for ubiquitination and subsequent degradation.

The Long and Viscous Road: Uncovering Nuclear Diffusion Barriers in Closed Mitosis [PDF]

, 2014
During Saccharomyces cerevisiae closed mitosis, parental identity is sustained by the asymmetric segregation of ageing factors. Such asymmetry has been hypothesized to occur via diffusion barriers, constraining protein lateral exchange in cellular ...

Intermediates in the assembly of mitotic checkpoint complexes and their role in the regulation of the anaphase-promoting complex

Proceedings of the National Academy of Sciences of the United States of America, 2016
Significance The mitotic checkpoint system has important roles to ensure accurate segregation of chromosomes in mitosis. This system regulates the activity of the ubiquitin ligase Anaphase-Promoting Complex/Cyclosome (APC/C) by the formation of ...

Epigenomics‐guided precision oncology: Chromatin variants in prostate tumor evolution

International Journal of Cancer, EarlyView.
Abstract Prostate cancer is a common malignancy that in 5%–30% leads to treatment‐resistant and highly aggressive disease. Metastasis‐potential and treatment‐resistance is thought to rely on increased plasticity of the cancer cells—a mechanism whereby cancer cells alter their identity to adapt to changing environments or therapeutic pressures to create

Spindle assembly checkpoint is sufficient for complete Cdc20 sequestering in mitotic control

Computational and Structural Biotechnology Journal, 2015
The spindle checkpoint assembly (SAC) ensures genome fidelity by temporarily delaying anaphase onset, until all chromosomes are properly attached to the mitotic spindle.

HIM-10 is required for kinetochore structure and function on Caenorhabditis elegans holocentric chromosomes. [PDF]

, 2001
Macromolecular structures called kinetochores attach and move chromosomes within the spindle during chromosome segregation. Using electron microscopy, we identified a structure on the holocentric mitotic and meiotic chromosomes of Caenorhabditis elegans ...

Cdc20 directs proteasome-mediated degradation of the tumor suppressor SMAR1 in higher grades of cancer through the anaphase promoting complex

Cell Death and Disease, 2017
The Tumor suppressor SMAR1 (scaffold matrix attachment region binding protein 1) has a crucial role in maintaining genomic stability, cell cycle progression and apoptosis.Our previous finding showed that it is highly suppressed in higher grade of cancer.

Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius
