The Proteasome02:18

The Proteasome

10.5K
Eukaryotic cells can degrade proteins through several pathways. One of the most important amongst 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. A series of enzymes carry out the ubiquitination of the target proteins - E1 (ubiquitin-activating enzyme), E2 (ubiquitin-conjugating enzyme), and E3...

Protein Complexes with Interchangeable Parts

3.0K
Groups of proteins may form a complex where each protein in this complex has a different role in the overall execution of the complex’s function. Often some of the proteins in the complex can be replaced by a closely related variant to give a complex that contains many of the same components yet is functionally distinct.
The SCF ubiquitin ligase is a protein complex of five individual proteins. This complex attaches ubiquitin to other target proteins to mark them for degradation. In order...

Overview of Secretory Vesicles01:33

Overview of Secretory Vesicles

9.8K
Secretory vesicles, also known as dense core vesicles (DCVs), are membrane-bound vesicles that transport secretory proteins, such as hormones or neurotransmitters. Regulated secretory vesicles transport proteins from the trans-Golgi network to the exterior of the cell. Proteins present in regulated secretory vesicles are required to be rapidly exocytosed in large amounts upon a specific stimulus.
Various proteins regulate the aggregation of molecules inside the secretory vesicles. Chromogranins...

Area of Science:

  • Biomimetic chemistry
  • Synthetic biology
  • Materials science

Background:

  • Developing artificial cells (protocells) requires compartmentalization for organizing biochemical reactions.
  • Hierarchically structured protocells with multiple, distinct compartments are challenging to synthesize.

Purpose of the Study:

  • To develop a facile method for creating hierarchically organized multicompartmentalized proteinosomes.
  • To control the encapsulation and release of biomolecules within these structures for protocell development.

Main Methods:

  • Utilized a recursive Pickering emulsion procedure with amphiphilic protein-polymer nanoconjugates.
  • Engineered host and guest proteinosomes with responsive membranes (protease-cleavable or disulfide cross-linked).
  • Controlled the number of guest proteinosomes within host proteinosomes.

Main Results:

  • Successfully synthesized hierarchically organized multicompartmentalized proteinosomes.
  • Demonstrated controlled encapsulation of enzymes and genetic polymers in targeted subcompartments.
  • Showcased three distinct spatiotemporal release profiles (retarded, synchronous, hierarchical) of dextran and DNA.

Conclusions:

  • The developed method provides a route to chemically and spatially organized multi-tiered synthetic protocells.
  • This work represents a significant step towards constructing functional synthetic protocells with integrated proto-organelles.
