Expression and Characterization of Relaxin Family Peptide Receptor 1 Variants
G-protein coupled receptors (GPCR) transduce extracellular stimuli into the cell interior and are thus centrally involved in almost all physiological-neuronal processes.

In conjunction with the endothelin (ET) type A (ETAR) and type B (ETBR) receptors, angiotensin (AT) type 1 (AT1R) and type 2 (AT2R) receptors, are peptide-binding class A G-protein-coupled receptors (GPCRs) acting in a physiologically overlapping context.

Phytochromes in Agrobacterium fabrum
The focus of this review is on the phytochromes Agp1 and Agp2 of Agrobacterium fabrum. These are involved in regulation of conjugation, gene transfer into plants, and other effects. Since crystal structures of both phytochromes are known, the phytochrome

Alternative polyadenylation (APA) is widespread among metazoans and has been shown to have important impacts on mRNA stability and protein expression. Beyond a handful of well-studied organisms, however, its existence and consequences have not been well ...

Reconsidering Spatial Priors In EEG Source Estimation: Does White Matter Contribute to EEG Rhythms? [PDF]
Electroencephalogram (EEG) has been a core tool used in functional neuroimaging in humans for nearly a hundred years. Because it is inexpensive, easy to implement, and noninvasive, it also represents an excellent candidate modality for use in the BCI setting. Nonetheless, a complete understanding of how EEG measurements (voltage fluctuations) relate to

Dynamic receptor team formation can explain the high signal transduction gain in E. coli [PDF]
Evolution has provided many organisms with sophisticated sensory systems that enable them to respond to signals in their environment. The response frequently involves alteration in the pattern of movement, such as the chemokinesis of the bacterium Escherichia coli, which swims by rotating its flagella.

Roots of diversity relations [PDF]
The species-area relationship is one of the central generalizations in ecology however its origin has remained a puzzle. Since ecosystems are understood as energy transduction systems, the regularities in species richness are considered to result from ubiquitous imperatives in energy transduction.

Lrp, a global regulator, regulates the virulence of Vibrio vulnificus
Background An attenuated mutant (designated NY303) of Vibrio vulnificus, which causes serious wound infection and septicemia in humans, was isolated fortuitously from a clinical strain YJ016.

Maxwell's demon in biochemical signal transduction with feedback loop [PDF]
Signal transduction in living cells is vital to maintain life itself, where information transfer in noisy environment plays a significant role. In a rather different context, the recent intensive researches of "Maxwell's demon" - a feedback controller that utilizes information of individual molecules - has led to a unified theory of information and ...

Structural snapshot of a bacterial phytochrome in its functional intermediate state
Phytochromes are photoreceptors that are present in plants, bacteria and fungi. Here the authors present crystal structures of the phytochrome Agp2 from Agrobacterium fabrum in the parent Pfr state as well as a functional Meta-F intermediate and discuss ...
