Common transthyretin-derived amyloid fibril structures in patients with hereditary ATTR amyloidosis

open access: yesNature Communications, 2023
Systemic ATTR amyloidosis is an increasingly important protein misfolding disease that is provoked by the formation of amyloid fibrils from transthyretin protein.

Comparative biochemistry of antarctic proteins

open access: yesComparative Biochemistry and Physiology Part A: Physiology, 1976
The UCD team of agricultural scientists has been studying the proteins of Antarctic species for 11 years, starting in 1964. During the first seven years, trips were made each year to Antarctica to study and obtain specimens from penguins and cold-adapted fishes.

Development of an automated multienzymatic biosensor for risk assessment of pesticide contamination in water and food

open access: yesEFSA Journal, 2018
The goal of this research is to better address the problems related to the widespread presence of pesticides in the environment. Despite the unquestionable utility of the pesticides against various pests in the agricultural field, most pesticides and the

Segmentation and morphological analysis of amyloid fibrils from cryo-EM image data

open access: yesJournal of Mathematics in Industry, 2023
Fast assessment of the composition of amyloid fibril samples from cryo-EM data poses a serious challenge to existing image analysis tools. We develop a method for automated segmentation of single fibrils requiring only little user input during the ...

Evolution of an extreme hemoglobin phenotype contributed to the sub-Arctic specialization of extinct Steller’s sea cows

open access: yeseLife, 2023
The extinct Steller’s sea cow (Hydrodamalis gigas; †1768) was a whale-sized marine mammal that manifested profound morphological specializations to exploit the harsh coastal climate of the North Pacific.

Golgi membrane fission requires the CtBP1-S/BARS-induced activation of lysophosphatidic acid acyltransferase δ

open access: yesNature Communications, 2016
CtBP1-S/BARS is required for fission of endomembrane compartments including the Golgi. Here the authors show that CtBP1-S/BARS activates a trans-Golgi lysophosphatidic acid acyltransferase that catalyses the production of phosphatidic acid and is ...

Cryo-EM structure and polymorphic maturation of a viral transduction enhancing amyloid fibril

open access: yesNature Communications, 2023
Amyloid fibrils have emerged as innovative tools to enhance the transduction efficiency of retroviral vectors in gene therapy strategies. In this study, we used cryo-electron microscopy to analyze the structure of a biotechnologically engineered peptide ...

Rapid assessment of DCLK1 inhibitors using a peptide substrate mobility shift assay

open access: yesSTAR Protocols, 2021
Summary: Peptide mobility shift assays provide a sensitive measure of kinase enzymatic activity and can be used to evaluate kinase inhibitors. Herein, we describe a protocol adapted for rapid assessment of doublecortin-like kinase inhibitors.

MHC class II complexes sample intermediate states along the peptide exchange pathway

open access: yesNature Communications, 2016
MHCII proteins bind and present both foreign and self-antigens to potentially activate CD4+ T cells via cognate T cell receptors (TCRs) during the adaptive immune response.
