The Sheaths of Methanospirillum Are Made of a New Type of Amyloid Protein

open access: yesFrontiers in Microbiology, 2018
The genera Methanospirillum and Methanosaeta contain species of anaerobic archaea that grow and divide within proteinaceous tubular sheaths that protect them from environmental stressors.

The RHIM of the Immune Adaptor Protein TRIF Forms Hybrid Amyloids with Other Necroptosis-Associated Proteins

open access: yesMolecules, 2022
TIR-domain-containing adapter-inducing interferon-β (TRIF) is an innate immune protein that serves as an adaptor for multiple cellular signalling outcomes in the context of infection. TRIF is activated via ligation of Toll-like receptors 3 and 4.

Exploring the sequence–structure relationship for amyloid peptides [PDF]

open access: yes, 2012
Amyloid fibril formation is associated with misfolding diseases, as well as fulfilling a functional role. The cross-β molecular architecture has been reported in increasing numbers of amyloid-like fibrillar systems. The Waltz algorithm is able to predict

In Situ Characterization of Hfq Bacterial Amyloid: A Fourier-Transform Infrared Spectroscopy Study

open access: yesPathogens, 2019
Hfq is a bacterial protein that regulates gene expression at the post-transcriptional level in Gram-negative bacteria. We have previously shown that Escherichia coli Hfq protein, and more precisely its C-terminal region (CTR), self-assembles into an ...

Neutron diffraction reveals sequence-specific membrane insertion of pre-fibrillar islet amyloid polypeptide and inhibition by rifampicin [PDF]

open access: yes, 2005
Human islet amyloid polypeptide (hIAPP) forms amyloid deposits in non-insulin-dependent diabetes mellitus (NIDDM). Pre-fibrillar hIAPP oligomers (in contrast to monomeric IAPP or mature fibrils) increase membrane permeability, suggesting an important ...

Functional amyloid [PDF]

open access: yesPrion, 2010
Evidence is growing at an increasing -pace that amyloid fibers are not just the result of aberrant protein folding associated with neurodegenerative diseases, but are widespread in nature for beneficial reasons. Amyloid is an attractive building material because its robust design and simple repetitive structure make for very durable and metabolically ...

Amyloid tracers detect multple binding sites in Alzheimer´s disease brain tissue. [PDF]

open access: yes, 2013
Imaging fibrillar amyloid-β deposition in the human brain in vivo by positron emission tomography has improved our understanding of the time course of amyloid-β pathology in Alzheimer’s disease. The most widely used amyloid-β imaging tracer so far is 11C-

Zinc–dysprosium functionalized amyloid fibrils [PDF]

open access: yesDalton Transactions, 2019
The heterometallic Zn 2 Dy 2 entity bearing partially saturated metal centres covalently decorates a highly ordered amyloid fibril core and the functionalised assembly exhibits catalytic Lewis acid behaviour.

Heterotypic interactions in amyloid function and disease [PDF]

open access: yesThe FEBS Journal, 2021
Amyloid aggregation results from the self‐assembly of identical aggregation‐prone sequences into cross‐beta‐sheet structures. The process is best known for its association with a wide range of human pathologies but also as a functional mechanism in all kingdoms of life.

The activity of amyloid beta binding alcohol dehydrogenase in Alzheimer's disease [PDF]

open access: yes, 2012
The mitochondria are a vibrant hub for many problems that occur in Alzheimer’s disease. The enzyme amyloid-ß binding alcohol dehydrogenase (ABAD) and Cyclophilin D (CypD) are two key mitochondrial proteins that have essential functions in Alzheimer’s ...
