ProteomicsLoss of H3K9 tri-methylation alters mitotic chromosome compaction and transcription factor retention during mitosis
Recent studies have shown that repressive chromatin machinery, including DNA methyltransferases (DNMTs) and Polycomb Repressor Complexes (PRCs), bind to chromosomes throughout mitosis and their depletion results in increased chromosome size. Enzymes that catalyse H3K9 methylation, such as Suv39h1, S...

Pan-caspase inhibitor Z-VAD-fmk acts as an inhibitor of peptide:N-glycanase (NGLY1); an endoglycosidase which cleaves N-linked glycans from glycoproteins exported from the endoplasmic reticulum during ER-associated degradation (ERAD). Pharmacological N-glycanase inhibition by Z-VAD-fmk or siRNA knoc...

ProteomicsProteomics analysis of rat primary myocyte and neuron-myocyte co-cultures
Alterations in autonomic function are known to occur in cardiac conditions including sudden cardiac death. Cardiac stimulation via sympathetic neurons can potentially trigger arrhythmias. Dissecting direct neural-cardiac interactions at the cellular level is technically challenging and understudied ...

ProteomicsGrowth Rate Dependent and Nutrient-specific Gene Expression Resource Allocation in Fission Yeast
Cellular resources are limited and their relative allocation to gene expression programmes determines physiological states and global properties such as the growth rate. Quantitative studies using various growth conditions have singled out growth rate as a major physiological variable explaining rel...

ProteomicsNovel protein interaction network of human calcitonin receptor-like receptor revealed by label-free quantitative proteomics
Background : The G protein-coupled receptor (GPCR) calcitonin receptor-like receptor (CLR) is implicated in cardiovascular and skin diseases, migraine and cancer. Beyond its agonists, receptor activity-modifying proteins and receptor component protein, interacting partners of this GPCR (‘CLR interac...

ProteomicsCaspr2 interacts with type 1 inositol 1,4,5-trisphosphate receptor in the developing cerebellum and regulates Purkinje cell morphology
Contactin-associated protein-like 2 (Caspr2) is a neurexin-like protein that has been associated with numerous neurological conditions. However, the mechanisms underlying Caspr2 function in the central nervous system remain incompletely understood. Here, we report on a functional role for Caspr2 in ...

ProteomicsCritical role of the UBL-domain in stimulating the E3 ubiquitin ligase activity of UHRF1 towards chromatin
The RING E3 ubiquitin ligase UHRF1 controls DNA methylation through its ability to target the maintenance DNA methyltransferase DNMT1 to newly replicated chromatin. DNMT1 recruitment relies on ubiquitylation of histone H3 by UHRF1, however, how UHRF1 deposits ubiquitin onto the histone is unknown. H...

ProteomicsAnalysis of factors bound to native metaphase ESC chromosomes following purification by flow cytometry
Stem cells are able to self-renew and also generate differentiated progeny. How gene expression patterns are transmitted through mitosis remains unresolved. Conventional studies have relied upon rigorous cell-cycle-stage synchronisation to find factors in mitotic lysates that could ‘bookmark’ the ge...

ProteomicsPhosphoproteomics of DNA repair in Saccharomyces cerevisisae
The role of Rad53 in response to a DNA lesion is central for the accurate orchestration of the DNA damage response. Rad53 activation relies on its phosphorylation by the Mec1 kinase and its own autophosphorylation in a manner dependent on the adaptor Rad9. While the mechanism behind Rad53 phosphoryl...

Understanding how the microbiota produces regulatory metabolites is of significance for cancer and cancer therapy. Using a host-microbe-drug-nutrient 4-way screening approach, we evaluated the role of nutrition at the molecular level in the context of 5-fluorouracil toxicity. Notably, our screens...
