Small cationic antimicrobial peptides delocalize peripheral membrane proteins

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2014
Significance Multidrug-resistant bacteria present an acute problem to medicine, generating interest in novel antimicrobial strategies. Antimicrobial peptides currently are being investigated, both as antibiotics and as immunomodulatory agents.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

open access: yesFEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Highly ordered clustering of TNFα and BAFF ligand-receptor-intracellular adaptor complexes on a lipid membrane

open access: yesNature Communications
The TNF family plays a critical role in immune regulation. Here, we present high-resolution structures of clusters formed by two TNF receptor family proteins, TNFR1 and BAFFR. Using a lipid monolayer method to mimic their membrane-bound state, we observe

Aspergillus fumigatus Infection-Induced Neutrophil Recruitment and Location in the Conducting Airway of Immunocompetent, Neutropenic, and Immunosuppressed Mice

open access: yesJournal of Immunology Research, 2018
Susceptibility to fungal infection is commonly associated with impaired neutrophil responses. To study the mechanisms underlying this association, we investigated neutrophil recruitment to the conducting airway wall after Aspergillus fumigatus conidium ...

Visualizing Ligand Binding to a GPCR In Vivo Using NanoBRET

open access: yesiScience, 2018
Summary: The therapeutic action of a drug depends on its ability to engage with its molecular target in vivo. However, current drug discovery strategies quantify drug levels within organs rather than determining the binding of drugs directly to their ...

The Effect of Highly Hydroxylated Fullerenol C60(OH)36 on Human Erythrocyte Membrane Organization [PDF]

open access: yes, 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 ...

Basement membrane proteins

open access: yesKidney International, 1992
Basement membranes are heterogeneous, highly specialized, electron-dense structures constructed from components of extracellular matrix proteins 20 to 200nm in width. They provide anchorage for adjacent cells as well as stimuli for cell differentiation, cell migration, and cell phenotype.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

open access: yesFEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

GRK Mediates μ-Opioid Receptor Plasma Membrane Reorganization

open access: yesFrontiers in Molecular Neuroscience, 2019
Differential regulation of the μ-opioid receptor (MOP) has been linked to the development of opioid tolerance and dependence which both limit the clinical use of opioid analgesics.
