Ubiquitin signaling in cell cycle control and tumorigenesis

open access: yesCell Death and Differentiation, 2020
Cell cycle progression is a tightly regulated process by which DNA replicates and cell reproduces. The major driving force underlying cell cycle progression is the sequential activation of cyclin-dependent kinases (CDKs), which is achieved in part by the

Targeting of Fzr/Cdh1 for timely activation of the APC/C at the centrosome during mitotic exit

open access: yesNature Communications, 2016
The activity of the anaphase-promoting complex/cyclosome (APC/C) needs to be regulated in time and space to perform different functions. Here the authors show that Spd2 localizes the APC/C activator Fzr at the centrosomes to promote optimal APC/C ...

Identification of calpain cleavage sites in the G1 cyclin-dependent kinase inhibitor p19(INK4d) [PDF]

open access: yes, 2006
Calpains are a large family of Ca2+-dependent cysteine proteases that are ubiquitously distributed across most cell types and vertebrate species. Calpains play a role in cell differentiation, apoptosis, cytoskeletal remodeling, signal transduction and ...

Conditional control of fluorescent protein degradation by an auxin-dependent nanobody

open access: yesNature Communications, 2018
Current approaches to conditionally deplete target proteins require site-specific genetic engineering or have poor temporal control. Here the authors overcome these limitations by combining the AID system with nanobodies to reversibly degrade GFP-tagged ...

The zinc finger transcription factor PW1/PEG3 restrains murine beta cell cycling [PDF]

open access: yes, 2016
Aims/hypothesis: Pw1 or paternally-expressed gene 3 (Peg3) encodes a zinc finger transcription factor that is widely expressed during mouse embryonic development and later restricted to multiple somatic stem cell lineages in the adult.

Phosphotransferase-dependent accumulation of (p)ppGpp in response to glutamine deprivation in Caulobacter crescentus

open access: yesNature Communications, 2016
The small molecule (p)ppGpp is commonly produced by bacteria as a signal of nutrient starvation. Here, Ronneau et al. show that (p)ppGpp accumulation in the model bacterium Caulobacter crescentusis modulated by a nitrogen-related phosphotransferase ...

Identification of ubiquitin-proteasome system components affecting the degradation of the transcription factor Pap1

open access: yesRedox Biology, 2020
Signaling cascades respond to specific inputs, but also require active interventions to be maintained in their basal/inactive levels in the absence of the activating signal(s).

Comparing Mitochondrial Activity, Oxidative Stress Tolerance, and Longevity of Thirteen Ascomycota Yeast Species

open access: yesAntioxidants, 2023
Aging is characterized by a number of hallmarks including loss of mitochondrial homeostasis and decay in stress tolerance, among others. Unicellular eukaryotes have been widely used to study chronological aging.

The contribution of age structure to cell population responses to targeted therapeutics [PDF]

open access: yes, 2012
Cells grown in culture act as a model system for analyzing the effects of anticancer compounds, which may affect cell behavior in a cell cycle position-dependent manner.

Metabolic control of cell division in α-proteobacteria by a NAD-dependent glutamate dehydrogenase

open access: yesCommunicative & Integrative Biology, 2016
Prior to initiate energy-consuming processes, such as DNA replication or cell division, cells need to evaluate their metabolic status. We have recently identified and characterized a new connection between metabolism and cell division in the α ...
