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 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 ... -
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 ... -
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. ... -
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 ... -
Apaf-1 Inhibitors Protect from Unwanted Cell Death in In Vivo Models of Kidney Ischemia and Chemotherapy Induced Ototoxicity
(Public Library Science, 2014-10-20)Background: Excessive apoptosis induces unwanted cell death and promotes pathological conditions. Drug discovery efforts aimed at decreasing apoptotic damage initially targeted the inhibition of effector caspases. Although ... -
Application of Solid Lipid Nanoparticles to Improve the Efficiency of Anticancer Drugs
(MDPI, 2019-03-22)Drug delivery systems have opened new avenues to improve the therapeutic effects of already-efficient molecules. Particularly, Solid Lipid Nanoparticles (SLNs) have emerged as promising nanocarriers in cancer therapy. SLNs ... -
ATP Antagonizes Thrombin-Induced Signal Transduction through 12(S)-HETE and cAMP
(Public Library of Science, 2013)In this study we have investigated the role of extracellular ATP on thrombin induced-platelet aggregation (TIPA) in washed human platelets. ATP inhibited TIPA in a dose-dependent manner and this inhibition was abolished ... -
BFL1 Modulates Apoptosis at the Membrane Level through a Bifunctional And Multimodal Mechanism Showing Key Differences With BCLXL
(Springer Nature, 2018-12-18)BFL1 is a relatively understudied member of the BCL2 protein family which has been implicated in the pathogenesis andchemoresistance of a variety of human cancers, including hematological malignancies and solid tumours. ... -
