Summary
Yeast lipid droplet-vacuole contact sites (vCLIP) are crucial for lipophagy. Their formation is regulated by metabolic cues and mediated by specific tethering proteins, revealing the molecular basis of this important cellular process.
Area of Science:
- Cell Biology
- Molecular Biology
- Yeast Genetics
Background:
- Lipid droplets and vacuoles form contact sites (vCLIP) in yeast.
- vCLIP formation is sensitive to metabolic conditions.
- vCLIP is linked to lipophagy, a specialized form of microautophagy.
Purpose of the Study:
- To elucidate the molecular mechanisms underlying vCLIP formation and function.
- To review recent advancements in understanding vCLIP.
- To identify future research directions in the field.
Main Methods:
- Literature review of studies on vCLIP.
- Analysis of molecular components involved in vCLIP formation.
- Discussion of metabolic regulation of vCLIP.
Main Results:
- vCLIP formation is mediated by lipid droplet proteins Ldo16 and Ldo45, and vacuolar protein Vac8.
- Ldo45 recruits phosphatidylinositol transfer protein Pdr16 to vCLIP.
- vCLIP assembly is dynamically regulated by cellular metabolic states.
Conclusions:
- The molecular players and regulation of vCLIP are now better understood.
- This knowledge advances our comprehension of lipid metabolism and autophagy.
- Further research will explore the detailed functions and regulation of vCLIP.

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...

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...

3.1K
Cells use energy-requiring bulk transport mechanisms to transfer large particles or large numbers of small particles into or out of the cell. The cells envelop the particles in spherical membranes called vesicles or vacuoles. Vesicles that transport material into the cell are built from the cell membrane. These vesicles encapsulate external molecules and transport them into the cell in a process called endocytosis.

3.3K
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...

7.4K
Membrane-enclosed structures called vesicles transport proteins and lipids across the cell. The vesicles derive their cargo from the plasma membrane, Golgi, ER, or endosome. Coated vesicles are spherical, protein-coated carriers with a 50–100 nm diameter that mediate bidirectional transport between the ER and the Golgi. The distribution of proteins between the ER and Golgi complex is dynamic and is maintained by different coated vesicles. Their formation is driven by the assembly of...

01:45Vesicular Tubular Clusters
2.3K
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.
