Amyloids are protein deposits linked to diseases like Alzheimer's and diabetes. Research explores their structure, formation, and role in both pathology and normal physiology, challenging disease-only associations.
Area of Science:
- Biochemistry
- Molecular Biology
- Pathology
Background:
- Amyloids are protein aggregates implicated in over 30 diseases, including neurodegenerative and systemic conditions.
- Protein misfolding and aggregation into beta-sheet structures are key features of amyloid diseases.
- Recent findings suggest intermediate aggregated states, not just insoluble polymers, may cause cellular toxicity.
Purpose of the Study:
- To summarize current knowledge on amyloidogenic peptides and proteins.
- To explore the occurrence, structure, folding pathways, chemistry, and biology of amyloids.
- To highlight factors influencing amyloid formation (amyloidogenesis).
Main Methods:
- Review of existing literature on amyloid formation and associated diseases.
- Analysis of in vitro studies on amyloidogenic peptides.
- Identification and characterization of non-pathological amyloidogenic proteins.
Main Results:
- Amyloids are filamentous protein deposits with diverse roles.
- Alpha-helix to beta-sheet transitions are implicated in amyloid formation.
- Non-pathological amyloids with physiological functions have been identified, broadening the understanding beyond disease.
Conclusions:
- Amyloid formation is a complex process influenced by various factors.
- Amyloids are not exclusively associated with disease; some have normal physiological roles.
- Further research is needed to fully understand the mechanisms and implications of amyloidogenesis.

Translocation of Proteins into the Mitochondria
Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...
