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 ...
Variability of indication criteria in knee and hip replacement: an observational study
(BioMed Central, 2010)
Background
Total knee (TKR) and hip (THR) replacement (arthroplasty) are effective surgical procedures that relieve pain, improve patients' quality of life and increase functional capacity. Studies on variations in medical ...
Noisy-threshold control of cell death
(BioMed Central, 2010)
Background
Cellular responses to death-promoting stimuli typically proceed through a differentiated multistage process, involving a lag phase, extensive death, and potential adaptation. Deregulation of this chain of events ...
Desarrollo de un nuevo soporte polímerico con componentes de matriz extracelular neural para su aplicación en la diferenciación "in vitro" de distintas células primarias
(2012-07-11)
Este trabajo de Tesis Doctoral presenta el desarrollo, la caracterización y la validación de un nuevo soporte polimérico capaz de inducir la diferenciación neuronal in vitro, combinando técnicas de fotolitografía y de ...
Caracterización estructural de complejos ribosomales de iniciación y de pre-translocación mediante microscopía electrónica
(Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitatearen Argitalpen Zerbitzua, 2012-07-04)
Los ribosomas son complejos macromoleculares altamente organizados responsables de la síntesis de proteínas en todos los organismos en un proceso llamado traducción. El término traducción hace referencia a que el lenguaje ...
