A Computational Module Assembled from Different Protease Family Motifs Identifies PI PLC from Bacillus cereus as a Putative Prolyl Peptidase with a Serine Protease Scaffold
(Public Library Science, 2013-08)Proteolytic enzymes have evolved several mechanisms to cleave peptide bonds. These distinct types have been systematically categorized in the MEROPS database. While a BLAST search on these proteases identifies homologous ... -
A fluorogenic cyclic peptide for imaging and quantification of drug-induced apoptosis
(Nature, 2020-08-12)Programmed cell death or apoptosis is a central biological process that is dysregulated in many diseases, including inflammatory conditions and cancer. The detection and quantification of apoptotic cells in vivo is hampered ... -
A key function for microtubule-associated-protein 6 in activity-dependent stabilisation of actin filaments in dendritic spines
(Nature Publishing, 2018-09-17)Emerging evidence indicates that microtubule-associated proteins (MAPs) are implicated in synaptic function; in particular, mice deficient for MAP6 exhibit striking deficits in plasticity and cognition. How MAP6 connects ... -
A novel RT-QPCR-based assay for the relative quantification of residue specific m6A RNA methylation
(Nature Publishing Group, 2019-12)N6-methyladenosine (m6A) is the most common and abundant RNA modification. Recent studies have shown its importance in the regulation of several biological processes, including the immune response, and different approaches ... -
A Proteomic Approach for Systematic Mapping of Substrates of Human Deubiquitinating Enzymes
(MDPI, 2021-05-03)The human genome contains nearly 100 deubiquitinating enzymes (DUBs) responsible for removing ubiquitin moieties from a large variety of substrates. Which DUBs are responsible for targeting which substrates remain mostly ... -
A Systematic Approach to Assess the Activity and Classification of PCSK9 Variants
(MDPI, 2021-12-18)Background: Gain of function (GOF) mutations of PCSK9 cause autosomal dominant familial hypercholesterolemia as they reduce the abundance of LDL receptor (LDLR) more efficiently than wild-type PCSK9. In contrast, PCSK9 ... -
Aberrant Synaptic PTEN in Symptomatic Alzheimer's Patients May Link Synaptic Depression to Network Failure
(Frontiers Media, 2021-05-11)In Alzheimer's disease (AD), Amyloid beta (A beta) impairs synaptic function by inhibiting long-term potentiation (LTP), and by facilitating long-term depression (LTD). There is now evidence from AD models that A beta ... -
Activation of the DnaK-ClpB Complex is Regulated by the Properties of the Bound Substrate
(Nature Publishing, 2018-04-11)The chaperone ClpB in bacteria is responsible for the reactivation of aggregated proteins in collaboration with the DnaK system. Association of these chaperones at the aggregate surface stimulates ATP hydrolysis, which ... -
Adenylate Cyclase Toxin promotes bacterial internalisation into non phagocytic cells
(Nature Publishing Group, 2015-09-08)Bordetella pertussis causes whooping cough, a respiratory infectious disease that is the fifth largest cause of vaccine-preventable death in infants. Though historically considered an extracellular pathogen, this bacterium ... -
Adenylate Cyclase Toxin Promotes Internalisation of Integrins and Raft Components and Decreases Macrophage Adhesion Capacity
(Public Library of Science, 2011-02-23)Bordetella pertussis, the bacterium that causes whooping cough, secretes an adenylate cyclase toxin (ACT) that must be post-translationally palmitoylated in the bacterium cytosol to be active. The toxin targets phagocytes ... -
Advantages and Versatility of Fluorescence-Based Methodology to Characterize the Functionality of LDLR and Class Mutation Assignment
(Public Library Science, 2014-11-11)Familial hypercholesterolemia (FH) is a common autosomal codominant disease with a frequency of 1:500 individuals in its heterozygous form. The genetic basis of FH is most commonly mutations within the LDLR gene. Assessing ... -
Affinity for the Interface Underpins Potency of Antibodies Operating In Membrane Environments
(Cell Press, 2020-08-18)The contribution of membrane interfacial interactions to recognition of membrane-embedded antigens by antibodies is currently unclear. This report demonstrates the optimization of this type of antibodies via chemical ... -
Agricultural Soils Amended with Thermally-Dried Anaerobically-Digested Sewage Sludge Showed Increased Risk of Antibiotic Resistance Dissemination
(Frontiers Media, 2021-04-28)The application of sewage sludge (SS) to agricultural soil can help meet crop nutrient requirements and enhance soil properties, while reusing an organic by-product. However, SS can be a source of antibiotic resistance ... -
An atlas of O-linked glycosylation on peptide hormones reveals diverse biological roles
(Nature, 2020-08-20)Peptide hormones and neuropeptides encompass a large class of bioactive peptides that regulate physiological processes like anxiety, blood glucose, appetite, inflammation and blood pressure. Here, we execute a focused ... -
An E2F7-Dependent Transcriptional Program Modulates DNA Damage Repair And Genomic Stability
(Oxford University Press, 2018-05-18)The cellular response to DNA damage is essential for maintaining the integrity of the genome. Recent evidence has identified E2F7 as a key player in DNA damage-dependent transcriptional regulation of cell-cycle genes. ... -
An Epilepsy-Causing Mutation Leads to Co-Translational Misfolding of the Kv7.2 Channel
(Springer, 2021-05-21)BACKGROUND: The amino acid sequence of proteins generally carries all the necessary information for acquisition of native conformations, but the vectorial nature of translation can additionally determine the folding outcome. ... -
Analysis of SUMOylated proteins using SUMO-traps
(Nature Publishing Group, 2013-04-22)SUMO-modified proteins are recognized by SUMO interacting motifs (SIMs), thus triggering diverse cellular responses. Here SIMs were used to develop SUMO-traps to capture endogenous SUMOylated proteins. Our results show ... -
