Role of Monoubiquitylation on the Control of IκBα Degradation and NF-κB Activity
(Public Library of Science, 2011-10-12)
The NF-κB pathway is regulated by multiple post-translational modifications including phosphorylation, ubiquitylation and SUMOylation. Many of these modifications act on the natural inhibitor IκBα modulating its capacity ...
Physico-chemical interactions between compartment-forming lipids and other prebiotically relevant biomolecules
(EDP Sciences, 2014)
Lipids are essential constituents of contemporary living cells, serving as structural molecules that are necessary to form membranous compartments. Amphiphilic lipid-like molecules may also have contributed to prebiotic ...
Data on interleukin (IL)-2- and IL-15-dependent changes in IL-2Rβ and IL-2Rγ complexes
(Elsevier, 2017-04)
We provide detailed datasets from our analysis of the proteins that associate with IL-2Rbeta and IL-2Rgamma in T-cells stimulated with IL-2 or IL-15 compared with resting T-cells, as identified by SILAC-based quantitative ...
Understanding the Mechanism of Translocation of Adenylate Cyclase Toxin across Biological Membranes
(MDPI, 2017-09-21)
Adenylate cyclase toxin (ACT) is one of the principal virulence factors secreted by the whooping cough causative bacterium Bordetella pertussis, and it has a critical role in colonization of the respiratory tract and ...
Functional organization of the HIV lipid envelope
(Nature, 2016-09-28)
The chemical composition of the human immunodeficiency virus type 1 (HIV-1) membrane is critical for fusion and entry into target cells, suggesting that preservation of a functional lipid bilayer organization may be required ...
Proteoliposomal formulations of an HIV-1 gp41-based miniprotein elicit a lipid-dependent immunodominant response overlapping the 2F5 binding motif
(2017-01-13)
The HIV-1 gp41 Membrane Proximal External Region (MPER) is recognized by broadly neutralizing antibodies and represents a promising vaccine target. However, MPER immunogenicity and antibody activity are influenced by ...
Structural changes induced by acidic pH in human apolipoprotein B-100
(Nature Research, 2016-11-08)
Acidification in the endosome causes lipoprotein release by promoting a conformational change in the LDLR allowing its recycling and degradation of LDL. Notwithstanding conformational changes occurring in the LDLR have ...
Identification and in vitro characterization of two new PCSK9 Gain of Function variants found in patients with Familial Hypercholesterolemia
(Nature, 2017-11)
Familial hypercholesterolemia (FH) is an autosomal dominant disease caused by pathogenic variants in genes encoding for LDL receptor (LDLR), Apolipoprotein B and Proprotein convertase subtilisin/kexin type 9 (PCSK9). Among ...
A global survey of CRM1-dependent nuclear export sequences in the human deubiquitinase family
(Portland Press LTD, 2012-01-01)
The mechanisms that regulate the nucleocytoplasmic localization of human deubiquitinases remain largely unknown. The nuclear export receptor CRM1 binds to specific amino acid motifs termed NESs (nuclear export sequences). ...
DNA methylation epigenotypes in breast cancer molecular subtypes
(BioMed Central, 2010-09-29)
Introduction: Identification of gene expression-based breast cancer subtypes is considered a critical means of prognostication. Genetic mutations along with epigenetic alterations contribute to gene-expression changes ...
