Detection of protein concentrations using a pH-step titration method [PDF]
, 1997 A stimulus-response method based on the application of a pH step is proposed for the detection of protein immobilized in a membrane on top of an ion-sensitive field-effect transistor (ISFET). The ISFET response to a step-wise change in pH, applied at the

Diffusion of Integral Membrane Proteins in Protein-Rich Membranes
The Journal of Physical Chemistry Letters, 2017 The lateral diffusion of embedded proteins along lipid membranes in protein-poor conditions has been successfully described in terms of the Saffman-Delbrück (SD) model, which predicts that the protein diffusion coefficient D is weakly dependent on its radius R as D ∝ ln(1/R).

Structure and function of H+/K+ pump mutants reveal Na+/K+ pump mechanisms
Nature Communications, 2022 Here, the authors study ion transport mechanisms by introducing mutations to convert an electroneutral proton/potassium pump into a prototypical electrogenic sodium/potassium pump, explaining their selectivity and phosphorylation mechanisms.

Polymer-encased nanodiscs with improved buffer compatibility
Scientific Reports, 2017 Styrene-maleic acid copolymers allow for solubilization and reconstitution of membrane proteins into nanodiscs. These polymer-encased nanodiscs are promising platforms for studies of membrane proteins in a near-physiologic environment without the use of ...

Rampant exchange of the structure and function of extramembrane domains between membrane and water soluble proteins. [PDF]
, 2013 Of the membrane proteins of known structure, we found that a remarkable 67% of the water soluble domains are structurally similar to water soluble proteins of known structure. Moreover, 41% of known water soluble protein structures share a domain with an

Modeling the Membrane Environment for Membrane Proteins [PDF]
Biophysical Journal, 2011 Increasingly, the membrane protein community is recognizing the sensitivity of protein structure and function to the protein's environment. Hofer et al. (1), in their recent Letter in the Biophysical Journal, aim to develop a crystallization protocol that will have increased biological relevance.

The Effect of Highly Hydroxylated Fullerenol C60(OH)36 on Human Erythrocyte Membrane Organization [PDF]
, 2015 The mechanism of the interaction of highly hydroxylated fullerenol C60(OH)36 with erythrocyte membranes was studied by electron spin resonance spectroscopy (ESR) of stearic acid derivatives labeled with a nitroxyl radical at C-12 or C-16 and with a ...

Substrate-induced conformational dynamics of the dopamine transporter
Nature Communications, 2019 The dopamine transporter is responsible for termination of neurotransmission through Na+-driven reuptake of neurotransmitter from the extracellular space. Here authors use hydrogen-deuterium exchange mass spectrometry to monitor Na+- and dopamine-induced

Membrane systems with proteins embedded in membranes
Theoretical Computer Science, 2008 Membrane computing is a biologically inspired computational paradigm. Motivated by brane calculi we investigate membrane systems which differ from conventional membrane systems by the following features: (1) biomolecules (proteins) can move through the regions of the systems, and can attach onto (and de-attach from) membranes, and (2 ...
