In vivo and in vitro Studies of Adaptor-clathrin Interaction
Published on: January 26, 2011
Summary
Clathrin coats reversibly dissociate into triskelions, revealing their structure. These triskelions are key to understanding intracellular transport and coated vesicle dynamics.
Area of Science:
- Cell Biology
- Molecular Biology
- Biochemistry
Background:
- Clathrin is a major protein forming coated pits and vesicles essential for intracellular transport.
- Coated vesicle function requires coordinated clathrin coat assembly/disassembly with membrane fusion/fission.
- Understanding clathrin structure and interactions is crucial for elucidating these molecular mechanisms.
Purpose of the Study:
- To investigate the molecular structure of clathrin coats.
- To understand the self-assembly and interactions of clathrin for intracellular transport.
Main Methods:
- Purification of clathrin coats.
- Analysis of coat dissociation products.
- Determination of molecular weight of dissociation products.
Main Results:
- Purified clathrin coats reversibly dissociate into triskelions.
- Triskelions consist of three flexible legs radiating from a central point.
- Triskelions are composed of clathrin trimers and light molecular weight polypeptides.
Conclusions:
- Clathrin coats are formed from dissociable triskelion units.
- The triskelion structure provides insight into clathrin coat assembly and function.
- Further research into clathrin-protein interactions is needed for a complete understanding of intracellular transport.

00:59COP Coated Vesicles
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 different...
01:32Pinching-off of Coated Vesicles
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...
01:33Coat Assembly and GTPases
Vesicles incorporate different coat protein subunits in different cell locations, which changes the properties of the coat, such as the shape and geometry of the transport vesicles. Thus, vesicle coat proteins also play a significant role in cargo selection.
Coat assembly depends on the local availability of phosphatidylinositol phosphates or PIPs and GTP-binding proteins. Adaptor proteins, which link the coat proteins to the membrane, bind to these PIPs and play a crucial role in controlling...

01:45Vesicular Tubular Clusters
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.

01:12Clathrin Coated Vesicles
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...
01:30Assembly of Signaling Complexes
Multiprotein signaling complexes are formed in a dynamic process involving protein-protein interactions at the cytoplasmic domain of transmembrane receptors or enzymatic and non-enzymatic proteins associated with the receptor. These complexes ensure the activation and propagation of intracellular signals that regulate cell functions.
