Structural Basis for Feed-Forward Transcriptional Regulation of Membrane Lipid Homeostasis in Staphylococcus aureus
(Public Library of Science, 2013-01-03)
The biosynthesis of membrane lipids is an essential pathway for virtually all bacteria. Despite its potential importance for the development of novel antibiotics, little is known about the underlying signaling mechanisms ...
RARRES3 suppresses breast cancer lung metastasis by regulating adhesion and differentiation
(Wiley Blackwell, 2014-07)
In estrogen receptor-negative breast cancer patients, metastatic relapse usually occurs in the lung and is responsible for the fatal outcome of the disease. Thus, a better understanding of the biology of metastasis is ...
Optimal Resting-Growth Strategies of Microbial Populations in Fluctuating Environments
(Public Library of Science, 2011-04-15)
Bacteria spend most of their lifetime in non-growing states which allow them to survive extended periods of stress and starvation. When environments improve, they must quickly resume growth to maximize their share of limited ...
Randomized, double-blind, placebo-controled clinical trial of sublingual immunotherapy in natural rubber latex allergic patients
(BioMed Central, 2011-08-09)
Background: Natural rubber latex allergy is a common and unsolved health problem. Since the avoidance of exposure is very difficult, immunotherapy is strongly recommended, but before its use in patients, it is essential ...
The Cryo-EM Structure of a Complete 30S Translation Initiation Complex from Escherichia coli
(Public Library of Science, 2011-07-05)
Formation of the 30S initiation complex (30S IC) is an important checkpoint in regulation of gene expression. The selection of mRNA, correct start codon, and the initiator fMet-tRNA(fMet) requires the presence of three ...
Pivoting between Calmodulin Lobes Triggered by Calcium in the Kv7.2/Calmodulin Complex
(Public Library Science, 2014-01-28)
Kv7.2 (KCNQ2) is the principal molecular component of the slow voltage gated M-channel, which strongly influences neuronal excitability. Calmodulin (CaM) binds to two intracellular C-terminal segments of Kv7.2 channels, ...
Control of gene expression by modulated self-assembly
(Oxford University Press, 2011-09)
Numerous transcription factors self-assemble into different order oligomeric species in a way that is actively regulated by the cell. Until now, no general functional role has been identified for this widespread process. ...
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 ...
Molecular determinants of Kv7.2 surface expression
(2014-02-25)
El objetivo de esta tesis ha sido esclarecer las bases moleculares de la expresión en membrana de los canales M neuronales, crucial para una mejor comprensión de su funcionamiento. La densidad de canales en superficie se ...
Structural characterization of helices A and B of Kv7.2 channel bound to Calmodulin. The calcium effect
(2015-12-15)
Los canales neuronales heterodiméricos Kv7.2 y Kv7.3 son el sustrato molecular de la corriente depotasio no-inactivante dominada ¿Corriente M¿. Ésta juega un papel crítico en el control de laexcitabilidad neuronal. Su mal ...
