Summary
Two studies reveal VPS13 proteins
Area of Science:
- Cell biology
- Molecular biology
- Protein localization
Background:
- VPS13 proteins are conserved and found at membrane contact sites.
- Their precise function and regulation remain unclear.
Purpose of the Study:
- To elucidate the regulatory mechanisms and functional roles of VPS13 proteins.
- To understand how VPS13 proteins are localized to different cellular compartments.
Main Methods:
- Investigated yeast Vps13p localization using competitive adaptors.
- Employed biochemical and structural analyses of VPS13 proteins.
Main Results:
- Competitive adaptors dictate the distinct localization patterns of yeast Vps13p.
- Provided evidence for VPS13 proteins' role in nonvesicular phospholipid transport.
Conclusions:
- VPS13 protein localization is controlled by competitive adaptors.
- VPS13 proteins are key mediators of nonvesicular lipid transfer.

01:19Contact-dependent Signaling
47.5K
Contact-dependent signaling, as the name suggests, requires that communicating cells be in direct contact with each other. This is achieved either through receptor-ligand interactions or by specialized cytoplasmic channels that allow the flow of small molecules between cells. In animal cells, channels called gap junctions facilitate contact-dependent signaling in certain tissues, whereas, plasmodesmata perform a similar function in plants.

Lipids include a diverse group of compounds that are largely nonpolar in nature. This is because they are hydrocarbons that include mostly nonpolar carbon-carbon or carbon-hydrogen bonds. Non-polar molecules are hydrophobic (“water fearing”), or insoluble in water. Lipids perform many different functions in a cell. Cells store energy for long-term use in the form of fats. Lipids also provide insulation from the environment for plants and animals. For example, they help keep aquatic...

01:13Contact Angle

When a solid is dipped inside a liquid, the liquid surface becomes curved near the contact. For some solid–liquid interfaces, the liquid is pulled up along the solid, while for others, the liquid surface is convex or depressed near the solid surface. This phenomenon can be explained using the concept of cohesive and adhesive forces.
The adhesive force is the molecular force between molecules of different materials, that is, between the molecules of the solid and the liquid. The cohesive...

Lipids are large molecules that are generally not water-soluble. Since most of the digestive enzymes in the human body are water-based, there are specific steps the body must take to break down lipids and make them available for use.
