Structural Characterisation of the Mammalian SRP Receptor
… interaction of the signal recognition particle (SRP), a ribonucleoprotein, with its receptor (SR). The eukaryotic SR is a heterodimeric protein consisting of SRα and SRβ which is anchored to the ER membrane. In all three kingdoms of life the conserved GTPases in SRP and SR (in eukaryotes SRP54 …

Unterschiedliche Funktionen von SRP und SecA beim Transport eines bakteriellen Proteins
… vom Signal recognition particle (SRP) erkannt; ihre Zielsteuerung und Integration in die Innenmembran erfolgen kotranslational und werden von SRP und seinem Rezeptor FtsY vermittelt. Sekretorische Proteine (lösliche periplasmatische Proteine und Aussenmembranproteine) werden am …

Using multiple layers and surface roughness control for improving the sensitivity of SRP sensors
Surface plasmon resonance (SPR) sensors have been developed quickly in the past twenty years in biosensing. However, the sensitivity of them restricts them from small molecular detection. This thesis focuses on the sensor chips of the SPR sensors and presents two potential methods to improve the …

The Effect of Orthodontic Treatment on Sagittal Root Position of the Maxillary Central Incisor
<p>Introduction: Sagittal root position (SRP) of maxillary incisors is an important factor in implant treatment planning. Kan et al defined four classes of SRP in an effort to aid implant placement treatment planning and these SRP classifications represent a novel approach to describing bone …

In vitro-Untersuchungen zum Sekretionsmechanismus der beta-Lactamase in Escherichia coli
… Das bakterielle signal recognition particle (SRP) und sein Rezeptor FtsY vermitteln die kotranslationale Zielsteuerung und Integration polytoper Innenmembranproteine an bzw. in das SecYEG-Translokon. <br>Nicht alle Innenmembranproteine sind jedoch ausschließlich auf SRP angewiesen. So ist die …

Analysis of essential structural and functional elements in the GTP-regulated signal recognition particle cycle
I have investigated signal recognition particle (SRP)-mediated protein targeting using a combination of genetic, biochemical, and molecular sequence analysis techniques. First, I consider the SRP cycle from the perspective of molecular evolution. This analysis provides insight into the significance …

Investigating the role of thalamic activity in visual cortical plasticity
… of stimulus-selective response plasticity (SRP). In SRP, neurons in the cortex alter their activity profile to a visual stimulus as it becomes familiar with repeated exposure. It requires the mechanisms of long-term potentiation (LTP), the basis for solidifying memories in the brain, which …

Service Recovery through Empowerment: HRM and Performance in the Hotel Sector
… empowerment and service recovery performance (SRP) in the three to five-star hotel sector in Sri Lanka. Because service recovery refers to how firms respond to service failures, this study focuses on the SRP of employees. Both qualitative and quantitative data were gathered through interviews, …

Biochemical and genetic analysis of a fission yeast ribonucleoprotein homologous to signal recognition particle
… complex known as signal recognition particle (SRP). SRP is composed of six polypeptides and one molecule of 7SL RNA. A homolog of mammalian SRP RNA was found in the fission yeast, Schizosaccharomyces pombe. The gene encoding the S. pombe RNA was cloned by screening a genomic library. Sequence …

Visual cortical plasticity : the role of parvalbumin expressing inhibitory neurons and abnormalities in models of neurodevelopmental disorders
… and stimulus-selective response potentiation (SRP) resulting from supplemental visual experience. These two forms of plasticity are triggered by different events but lead to a similar increase in visual cortical response. Both also require the NMDA class of glutamate receptor (NMDAR). However, …

Genetic analysis of Schizosaccharomyces pombe 7SL RNA
Signal recognition particle (SRP), a ribonucleoprotein composed of six polypeptides and one molecule of 7SL RNA, is required for translocation of secretory proteins into mammalian microsomal vesicles in vitro. In order to investigate the function of the RNA component of SRP, mutations were …

Highly Physical Solar Radiation Pressure Modeling During Penumbra Transitions
Solar radiation pressure (SRP) is one of the major non-gravitational forces acting on spacecraft. Acceleration by radiation pressure depends on the radiation flux; on spacecraft shape, attitude, and mass; and on the optical properties of the spacecraft surfaces. Precise modeling of SRP is needed …

Understanding experience-dependent plasticity of cellular and network activity in the mouse primary visual cortex
… is stimulus-selective response potentiation (SRP). SRP is induced simply through experience to the same gratings visual stimulus over days, resulting in potentiation of visually-evoked potentials (VEPs) in layer 4 of V1. Due to the lack of studies regarding the cellular and network activity …
