Protein crowding on biomembranes: analysis of contour instabilities
, 2014 Collective behavior of proteins on biomembranes is usually studied within the spontaneous curvature model. Here we consider an alternative phenomenological approach, which accounts consistently for partial ordering of proteins as well as the anchoring ...

Structure and function of bacterial dynamin-like proteins [PDF]
, 2012 Membrane dynamics are essential for numerous cellular processes in eukaryotic and prokaryotic cells. In eukaryotic cells, membrane fusion and fission are often catalyzed by large GTPases of the dynamin protein family. These proteins couple GTP hydrolysis

Cyclic nucleotide signaling as a drug target in retinitis pigmentosa
FEBS Letters, EarlyView.Disruptions in cGMP and cAMP signaling can contribute to retinal dysfunction and photoreceptor loss in retinitis pigmentosa. This perspective examines the mechanisms and evaluates emerging evidence on targeting these pathways as a potential therapeutic strategy to slow or prevent retinal degeneration.

How Carvedilol activates β2-adrenoceptors
Nature Communications, 2022 Carvedilol is among the most effective β-blockers for improving survival after myocardial infarction. Yet the mechanisms by which carvedilol achieves this superior clinical profile are still unclear.

Sorting pathways of mitochondrial inner membrane proteins [PDF]
, 1990 Two distinct pathways of sorting and assembly of nuclear-encoded mitochondrial inner membrane proteins are described. In the first pathway, precursor proteins that carry amino-terminal targeting signals are initially translocated via contact sites ...

Membrane Lipids and the Conformations of Membrane Proteins [PDF]
The Journal of General Physiology, 1969 The general relations between protein conformation and the optical activity of peptide chromophores are outlined and applied to the analysis of the optical rotatory dispersion and circular dichroism of the plasma membranes of human erythrocytes and Ehrlich ascites carcinoma cells.

TRAF2 binds to TIFA via a novel motif and contributes to its autophagic degradation
FEBS Letters, EarlyView.TRAF family members couple receptor signalling complexes to downstream outputs, but how they interact with these complexes is not always clear. Here, we show that during ADP‐heptose signalling, TRAF2 binding to TIFA requires two short sequence motifs in the C‐terminal tail of TIFA, which are distinct from the TRAF6 binding motif.

FEBS Letters, EarlyView.Exposure to common noxious agents (1), including allergens, pollutants, and micro‐nanoplastics, can cause epithelial barrier damage (2) in our body's protective linings. This may trigger an immune response to our microbiome (3). The epithelial barrier theory explains how this process can lead to chronic noncommunicable diseases (4) affecting organs ...

Biogenesis of mitochondrial porin [PDF]
, 1990 We review here the present knowledge about the pathway of import and assembly of porin into mitochondria and compare it to those of other mitochondrial proteins.

Rotational Diffusion of Membrane Proteins: Characterization of Protein-Protein Interactions in Membranes [PDF]
Biophysical Journal, 2012 It has long been appreciated that the rotational diffusion coefficient (Dr) and hence the rotational correlation time (τr) of a transmembrane protein about its membrane normal axis is predicted to be highly sensitive to its cylindrical radius (e.g., Saffman and Delbruck (1)). Due to the highly viscous nature of a cellular membrane or a membrane bilayer,
