Membrane morphologies induced by arc-shaped scaffolds are determined by arc angle and coverage [PDF]

open access: yes, 2019
The intricate shapes of biological membranes such as tubules and membrane stacks are induced by proteins. In this article, we systematically investigate the membrane shapes induced by arc-shaped scaffolds such as proteins and protein complexes with coarse-grained modeling and simulations.

A Mathematical Model for Predicting the Life of PEM Fuel Cell Membranes Subjected to Hydration Cycling [PDF]

open access: yesJournal of Power Sources 215 (2012) 135-144, 2013
Under typical PEM fuel cell operating conditions, part of membrane electrode assembly is subjected to humidity cycling due to variation of inlet gas RH and/or flow rate. Cyclic membrane hydration/dehydration would cause cyclic swelling/shrinking of the unconstrained membrane.

Membrane permeabilization by Islet Amyloid Polypeptide

open access: yes, 2009
Membrane permeabilization by Islet Amyloid Polypeptide (IAPP) is suggested to be the main mechanism for IAPP-induced cytotoxicity and death of insulin-producing -cells in type 2 diabetes mellitus (T2DM).

The Saccharomyces cerevisiae amino acid transporter Lyp1 has a broad substrate spectrum

open access: yesFEBS Letters, EarlyView.
In Saccharomyces cerevisiae, Yeast Amino acid Transporter family members mediate the import of amino acids, ranging from substrate specialists to generalists. Here, we show that the specialist transporter, Lyp1, has a broader substrate spectrum than previously described, with affinity constants spanning from micromolar to millimolar.

A Peptide‐Derived Aggregation‐Induced Emission Nanobioprobe: Unlocking Selective Detection of Fusobacterium nucleatum and Noninvasive Screening of Colorectal Cancer

open access: yesAggregate
Colorectal cancer (CRC) screening and early diagnosis is an effective strategy for reducing CRC mortality. However, the current detection methods involve exorbitant costs and complex procedures, which are inconvenient for large‐scale screening. Given its

Conformational plasticity of NaK2K and TREK2 potassium channel selectivity filters

open access: yesNature Communications, 2023
The potassium channel selectivity filter is responsible for conduction and selectivity of K + over other cations. Here, the authors use a combination of single molecule FRET, non-canonical fluorescent amino acid incorporation, and single channel patch ...

Spatial Dynamic Structures and Mobility in Computation [PDF]

open access: yesarXiv, 2011
Membrane computing is a well-established and successful research field which belongs to the more general area of molecular computing. Membrane computing aims at defining parallel and non-deterministic computing models, called membrane systems or P Systems, which abstract from the functioning and structure of the cell.

Modeling membrane nanotube morphology: the role of heterogeneity in composition and material properties. [PDF]

open access: yes, 2020
Membrane nanotubes are dynamic structures that may connect cells over long distances. Nanotubes are typically thin cylindrical tubes, but they may occasionally have a beaded architecture along the tube.

Sites of Biosynthesis of Outer and Inner Membrane Proteins of Neurospora crassa Mitochondria [PDF]

open access: yes, 1970
Outer and inner membranes of Neurospora crassa mitochondria were separated by the combined swelling, shrinking, sonication procedure. Membranes were characterized by electron microscopy and by marker enzyme activities.
