Amyloid Fibrils03:03

Amyloid Fibrils

10.3K
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 Modifications in the RER01:26

Protein Modifications in the RER

5.7K
Modification of secretory and transmembrane proteins entering the rough ER begins in the ER lumen. These modifications aid in protein folding and stabilize the acquired tertiary structure. Protein modifications in the rough ER co-occur at different stages of protein folding.
Broadly, these modifications can be categorized into four main categories — glycosylation, formation of disulfide bonds, assembly of protein subunits, and specific proteolytic cleavages like removal of signal...

ATP Synthase: Mechanism01:48

ATP Synthase: Mechanism

16.0K
In animals, the mitochondrial F1F0 ATP synthase is the key protein that synthesizes ATP molecules through a complex catalytic mechanism. While the nuclear genome encodes the majority of ATP synthase subunits, the mitochondrial genome encodes some of the enzyme's most critical components. The formation of this multi-subunit enzyme is a complex multi-step process regulated at the level of transcription, translation, and assembly. Defects in one or more of these steps can result in decreased...

Protein Folding Quality Check in the RER01:29

Protein Folding Quality Check in the RER

4.4K
ER is the primary site for the maturation and folding of soluble and transmembrane secretory proteins. The calnexin cycle is a specific chaperone system that folds and assesses the confirmation of N-glycosylated proteins before they can exit the ER lumen. The primary players of this quality check pipeline are the lectins, ER-resident chaperones, and a glucosyl transferase enzyme. In case the calnexin system in the lumen fails to salvage a misfolded protein, it is transported to the cytoplasm...

Neural Regulation01:37

Neural Regulation

34.8K
Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

The Early Endosome: Endocytosis of Transferrin01:28

The Early Endosome: Endocytosis of Transferrin

4.1K
Essential proteins such as insulin or low-density lipoprotein (LDL) and micronutrients such as iron enter a eukaryotic cell through receptor-mediated endocytosis. Subsequently, the early endosomes fuse with the vesicles containing such receptor-ligand complexes and play a vital role in sorting the incoming ligands and receptors. While the ligands are either degraded inside the vesicle or released into the cytosol, their receptors are returned to the plasma membrane for further rounds of...

  • Neurodegenerative Diseases

Background:

  • Many proteins implicated in neurodegenerative diseases, such as alpha-synuclein (α-synuclein), have poorly understood functions.
  • Alpha-synuclein is notably associated with Parkinson's disease and is now recognized as a metal-binding protein.
  • Its function may be linked to cofactor binding, with recent suggestions pointing to a specific catalytic activity.

Purpose of the Study:

  • To review the evidence for alpha-synuclein's proposed function in iron reduction.
  • To explore the implications of this function for understanding Parkinson's disease.

Main Methods:

  • This review synthesizes existing research and recent findings.
  • It discusses the catalytic activity of alpha-synuclein involving copper and iron reduction.
  • Evidence supporting this proposed function is critically examined.

  • The proposed function of alpha-synuclein in iron reduction offers a new perspective on its biological role.
  • Understanding this function may be crucial for unraveling the pathogenesis of Parkinson's disease.
  • Further research into alpha-synuclein's metal-binding properties and catalytic activities is warranted.
