Summary
Researchers developed a DNA-directed self-assembly method for creating hybrid vesicle-droplet structures. This controllable and reversible system enables the creation of complex modular materials with tunable properties.
Area of Science:
- Soft Matter Physics
- Materials Science
- Biotechnology
Background:
- Modular hybrid structures are crucial for advanced materials.
- Controlled self-assembly is key to creating complex systems.
- Giant unilamellar vesicles and emulsion droplets are versatile building blocks.
Discussion:
- Functionalized vesicles and droplets with DNA oligonucleotides and streptavidin linkers enable specific, reversible self-assembly.
- PEGylated phospholipids modulate system stability without interfering with DNA recognition.
- Heating the hybrid structures above DNA melting temperature in the presence of biotin reverses the assembly.
Key Insights:
- Demonstrated specific and reversible DNA-directed self-assembly of vesicle-droplet hybrid structures.

4.4K
Vesicle budding is orchestrated by distinct cytosolic proteins such as adaptor proteins, coat proteins, and GTPases. To initiate vesicle budding, membrane-bending proteins containing crescent-shaped BAR domains bind to the lipid heads in the bilayer and distort the membrane to form a protein-coated vesicle bud. Adaptors proteins such as AP2 for clathrin-coated vesicles can nucleate on the deformed membrane. Finally, coat proteins such as clathrin or COPI and COPII assemble into a coat forming...

01:43SNAREs and Membrane Fusion
13.3K
Once a transport vesicle has recognized its target organelle, the vesicular membrane needs to fuse with the target membrane to unload the cargo. Transmembrane proteins called SNAREs present on organelle membranes and their vesicles, mediate vesicle fusion.
SNAREs exist in pairs that symmetrically interact and catalyze the fusion of the lipid bilayers in vesicle and target organelle. v-SNARE in the vesicle membrane are single polypeptide chains that bind to a complementary t-SNARE, composed of 2...

01:45Vesicular Tubular Clusters
3.3K
After budding out from the ER membrane, some COPII vesicles lose their coat and fuse with one another to form larger vesicles and interconnected tubules called vesicular tubular clusters or VTCs. These clusters constitute a compartment at the ER-Golgi interface known as ERGIC (Endoplasmic Reticulum Golgi Intermediate Compartment). The ERGIC is a mobile membrane-bound cargo transport system that sorts proteins secreted from ER and delivers them to the Golgi.

02:41Protein Complex Assembly
17.1K
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.

Clathrin-coated vesicles use endocytosis to transport receptors and lysosomal hydrolases from the Golgi to the lysosome in the late secretory pathway. Clathrin-mediated endocytosis was the first described endocytic process, and Clathrin-coated vesicles remain one of the most well-studied transport vesicles. The molecular machinery that generates clathrin-coated vesicles comprises over 50 proteins that precisely coordinate vesicle formation. Cell surface receptors concentrated in indented sites...

01:38Intralumenal Vesicles and Multivesicular Bodies
5.2K
Intraluminal vesicles (ILVs) are small vesicles 50-80 nm in diameter formed during the maturation of early endosomes. A specialized endosome containing numerous ILVs is called a multivesicular body (MVB). ILVs contain internalized molecules such as antigens, nucleic acids, proteins, and metabolites. Some of these molecules are released from the MVBs inside exosomes and are transported to other cells. Other MVBs contain molecules that are retained in the ILVs and are later degraded within the...
