Membrane Lipids and the Conformations of Membrane Proteins [PDF]

open access: yesThe 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.

Biophysical approaches for studying viral entry

open access: yesFEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

open access: yesFEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

The styrene-maleic acid copolymer:: a versatile tool in membrane research [PDF]

open access: yes, 2016
A new and promising tool in membrane research is the detergent-free solubilization of membrane proteins by styrene-maleic acid copolymers (SMAs). These amphipathic molecules are able to solubilize lipid bilayers in the form of nanodiscs that are bounded ...

Lipids in membrane protein structures

open access: yesBiochimica et Biophysica Acta (BBA) - Biomembranes, 2004
This review describes the recent knowledge about tightly bound lipids in membrane protein structures and deduces general principles of the binding interactions. Bound lipids are grouped in annular, nonannular, and integral protein lipids. The importance of lipid binding for vertical positioning and tight integration of proteins in the membrane, for ...

Rab14 regulates the transport of human papillomavirus to the trans‐Golgi network for infectious cell entry

open access: yesFEBS Letters, EarlyView.
This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.

A proteomic analysis of lipid raft and GPI anchored proteins in Caenorhabditis elegans [PDF]

open access: yes, 2010
Glycosylphosphatidylinositol (GPI) anchored proteins are a unique group of membrane proteins found on the surface and certain intracellular compartments of eukaryotic cells.

Sex-specific lipidomic signatures in aortic valve disease reflect differential fibro-calcific progression

open access: yesNature Communications
Fibro-calcific aortic valve disease (FCAVD) is the most common valvular heart disease manifesting in pathological remodeling of the aortic valve (AV) leaflets, ultimately leading to aortic stenosis. Although dyslipidemia is a driver of FCAVD pathogenesis,

Comparison of coarse-grained and all-atom “membrane-solvent” systems as models of memcapacitors under alternating electric field [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Физика
Background and Objectives: The lipid membrane is one of the most important structures of a living cell, representing a barrier with selective permeability.

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

open access: yesFEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified
