Intrinsically Disordered Proteins02:18

Intrinsically Disordered Proteins

18.5K
Intrinsically disordered proteins are a group of proteins that do not fold into specific three-dimensional structures. Their structural flexibility allows them to complement ordered proteins to perform functions that are inaccessible to rigid structures. They are more common in eukaryotes than prokaryotes and may either be exclusively intrinsically disordered or hybrid proteins, consisting of a mix of ordered and disordered regions. The absence of a rigid structure in these proteins can be...

Amyloid Fibrils03:03

Amyloid Fibrils

10.5K
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 Assembly02:41

Protein Complex Assembly

12.4K
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...

The Unfolded Protein Response01:37

The Unfolded Protein Response

5.2K
The ER is the hub of protein synthesis in a cell. It has robust systems to quality control protein folding and also for degradation of terminally misfolded proteins. Under normal conditions, a small proportion of misfolded proteins that cannot be salvaged need to be transported to the cytoplasm by the ER-associated degradation or ERAD pathways. However, if the ERAD cannot handle the misfolded proteins, the cell activates the unfolded protein response or UPR to adjust the protein folding...

The Proteasome01:13

The Proteasome

1.2K
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...

Purpose of the Study:

  • To explore the multifaceted roles of IDPs in cellular processes and biological phenomena.
  • To propose a conceptual framework for understanding IDP functions despite their lack of structure.

Main Methods:

  • Review of existing literature on IDPs and cellular systems.
  • Conceptual modeling of IDPs as attractors and their role in noise amplification.

Main Results:

  • IDPs influence cell-fate decisions by managing protein interaction networks.
  • IDP conformational dynamics contribute to stochastic switching of cellular phenotypes.
  • IDPs may play roles in early life evolution, organelle formation, multicellularity, and inheritance.

Conclusions:

  • IDPs are critical for cellular decision-making and adaptability.
  • Understanding IDPs provides insights into fundamental biological processes from evolution to inheritance.
