Coordination of bilayer properties by an inward-rectifier K+ channel is a cooperative process driven by protein-lipid interaction

open access: yesJournal of Structural Biology: X
Physical properties of biological membranes directly or indirectly govern biological processes. Yet, the interplay between membrane and integral membrane proteins is difficult to assess due to reciprocal effects between membrane proteins, individual ...

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 ...

Yet more evidence that non-aqueous myelin lipids can be directly imaged with ultrashort echo time (UTE) MRI on a clinical 3T scanner: a lyophilized red blood cell membrane lipid study

open access: yesNeuroImage
Direct imaging of semi-solid lipids, such as myelin, is of great interest as a noninvasive biomarker of neurodegenerative diseases. Yet, the short T2 relaxation times of semi-solid lipid protons hamper direct detection through conventional magnetic ...

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.

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 ...

The effect of changes in plasma membrane lipid composition on the heat sensitivity of Hepatoma tissue culture cells and selected plasma membrane enzymes [PDF]

open access: yes, 1990
Hepatoma Tissue Culture (HTC) cells grown in the presence of 60µM arachidonic acid for 24, 36 and 48 hours became progressively more thermosensitive than control cells.

PLRP2 selectively localizes synaptic membrane proteins via acyl-chain remodeling of phospholipids

open access: yesJournal of Lipid Research, 2020
The plasma membrane of neurons consists of distinct domains, each of which carries specialized functions and a characteristic set of membrane proteins.

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

Digalactosyl-diacylglycerol-deficiency lowers the thermal stability of thylakoid membranes [PDF]

open access: yes, 2010
We investigated the effects of digalactosyl-diacylglycerol (DGDG) on the organization and thermal stability of thylakoid membranes, using wild-type Arabidopsis thaliana and the DGDG-deficient mutant, dgd1. Circular-dichroism measurements reveal that DGDG-

Diverse regulation of functional dimerization of a sugar transporter by different interfacial lipids

open access: yesNature Communications
Endogenous lipids play essential roles in modulating membrane protein structure and function, yet the molecular mechanisms governing lipid-specific regulation remain elusive.
