Amyloid Fibrils03:03

Amyloid Fibrils

12.9K
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 Folding

12.5K
Proteins are chains of amino acids linked together by peptide bonds. Upon synthesis, a protein folds into a three-dimensional conformation, critical to its biological function. Interactions between its constituent amino acids guide protein folding, and hence the protein structure is primarily dependent on its amino acid sequence.

Adaptability of Cytoskeletal Filaments

6.8K
The cytoskeleton is a complex dynamic structure performing varied functions based on cellular requirements. The adaptability of the individual filaments in the cytoskeleton determines their ability to perform various functions within the cell. It can undergo rapid reorganization during processes like cell division or remain stable for several hours as in the interphase. The adaptability of these filaments depends on stringent regulatory mechanisms. The microfilament and microtubules of the...

  • Alpha-synuclein (α-synuclein) is a protein found in the central nervous system, particularly at pre-synaptic terminals.
  • Its exact biological functions and native structure are not fully understood.
  • Debate exists regarding the natural conformation and multimeric assemblies of α-synuclein.

Purpose of the Study:

  • To review current evidence defining the physiological states of α-synuclein.
  • To highlight the role of α-synuclein's structural flexibility in health and disease.
  • To underscore the importance of understanding α-synuclein conformations for therapeutic strategies.

Main Methods:

  • Literature review of existing evidence on α-synuclein.
  • Analysis of studies investigating α-synuclein's native and pathological conformations.
  • Discussion of the structural flexibility of α-synuclein.

Main Results:

  • Evidence suggests α-synuclein can adopt various conformations, including amyloid-like fibrils and amorphous aggregates.
  • These aggregates are implicated in neuronal inclusions characteristic of Parkinson's disease.
