Summary
Dynamin, crucial for cellular internalization, interacts with actin-regulating proteins. This highlights dynamin
Area of Science:
- Cell Biology
- Molecular Biology
Background:
- Clathrin-mediated endocytosis is vital for protein/lipid internalization and synaptic vesicle recycling.
- The GTPase dynamin and its proline-rich domain are key regulators of endocytosis via protein-protein interactions.
- Dynamin indirectly influences actin dynamics through interactions with actin-binding proteins.
Purpose of the Study:
- To summarize dynamin's interactions with Src homology 3 (SH3)-containing proteins.
- To discuss the roles of newly identified dynamin-binding proteins, SPIN90/WISH and sorting nexin 9.
- To explore the link between endocytosis and actin dynamics.
Main Methods:
- Literature review of dynamin interactions.
- Analysis of protein-protein interaction networks involving dynamin and SH3 proteins.
- Discussion of the functional implications of identified dynamin-binding proteins.
Main Results:
- Dynamin interacts with numerous SH3-containing proteins, many of which are involved in actin regulation.
- SPIN90/WISH and sorting nexin 9 are newly identified dynamin-binding proteins.
- These interactions suggest a coordinated regulation of endocytosis and actin dynamics.
Conclusions:
- Dynamin plays a central role in linking endocytic events with cellular actin dynamics.
- SH3-containing proteins, including SPIN90/WISH and sorting nexin 9, mediate this connection.
- Understanding these interactions is crucial for comprehending cellular trafficking and organization.

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...
01:39Mechanism of Filopodia Formation
Filopodia are thin, actin-rich cellular protrusions that play an important role in many fundamental cellular functions. They vary in their occurrence, length, and positioning in different cell types, suggesting their diverse roles.
Their main function is to guide migrating cells during normal tissue morphogenesis or cancer metastasis by recognizing and making initial contacts with the extracellular matrix. However, they can also act as stationary cell anchors or help to establish communication...

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.

01:33Coat 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...

01:28Protein Translocation Machinery on the ER Membrane
The translocon complex situated on the ER membrane is the main gateway for the protein secretory pathway. It facilitates the transport of nascent peptides into the ER lumen and their insertion into the ER membrane.
Sec61 protein conducting channel
In eukaryotes, the translocon complex comprises a core heterotrimeric translocator channel called the Sec61 complex. This channel includes three transmembrane proteins, Sec61α, Sec61β, and Sec61γ, and is the largest subunit of the translocon complex.

01:43The Movement of Organelles and Vesicles
In eukaryotic cells, cytoskeletal filaments such as actin, microtubules, and intermediate filaments form a mesh-like cytoskeletal network. These filaments serve as tracks for transporting cellular cargo. Specialized motor proteins use the chemical energy stored in adenosine triphosphate (ATP) for this transport. During interphase, microtubules are polarized, with the plus-end towards the cell periphery and the minus-end towards the cell center. Two microtubule-associated motor proteins,...
