Amyloid Fibrils03:03

Amyloid Fibrils

12.4K
Amyloid fibrils are aggregates of misfolded proteins.  Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils. 
Amyloid deposits were observed as early as 1639 in the liver and the spleen.   In 1854, Rudolph Virchow performed iodine staining,...

Protein Complex Assembly

17.0K
Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types.  Most protein complexes self-assemble spontaneously via ordered pathways, while some proteins need assembly factors that guide their proper assembly. Despite the crowded intracellular environment, proteins usually interact with their correct partners and form functional complexes.
Many viruses self-assemble into a fully functional unit using the infected host cell to...

Proteins: From Genes to Degradation

14.8K
Within a biological system, the DNA encodes the RNA, and the nucleotide sequence in the RNA further defines the amino acid sequence in the protein. This is referred to as “The Central Dogma of Molecular Biology” - a term coined by Francis Crick.  Central dogma is a firm principle in biology that defines the flow of genetic information within any life form. The two fundamental steps in central dogma are - transcription and translation.
Transcription is the synthesis of RNA...

The Proteasome

1.9K
Eukaryotic cells can degrade proteins through several pathways. One of the most important among these is the ubiquitin-proteasome pathway. It helps the cell eliminate the misfolded, damaged, or unwarranted cytoplasmic proteins in a highly specific manner.
In this pathway, the target proteins are first tagged with small proteins called ubiquitin. This involves participation of a series of enzymes including— E1 (ubiquitin-activating enzyme), E2 (ubiquitin-conjugating enzyme), and E3...

Background:

  • Protein aggregation is a key feature of neurodegenerative diseases like Alzheimer's and Parkinson's.
  • It signifies a failure in cellular proteome management, specifically maintaining protein foldedness.
  • Cells normally prevent aggregation in crowded environments, but misfolded proteins are prone to aberrant interactions.

Purpose of the Study:

  • To review recent advancements in understanding proteostasis.
  • To discuss methods for monitoring proteostasis.
  • To explore the biological impact of protein aggregation and identify challenges.

Main Methods:

  • Literature review of proteostasis research.
  • Analysis of studies on protein folding pathways.
  • Examination of techniques for monitoring protein aggregation.

Main Results:

  • Proteostasis is crucial for preventing protein aggregation and maintaining cellular health.
  • Non-native protein conformations are particularly susceptible to aggregation.
  • Advances in monitoring proteostasis offer insights into disease mechanisms.
