Summary
Recycling endosomes, regulated by Rab11 GTPase and FIP3 proteins, are crucial for cell division. This study highlights their role in cytokinesis and abscission, detailing methods to analyze membrane and cytoskeleton dynamics.
Area of Science:
- Cell Biology
- Molecular Biology
Background:
- Recycling endosomes regulate cytokinesis and abscission.
- Rab11-endosomes transport proteins to the ingression furrow, establishing the abscission site.
- Rab11 GTPase interacts with effector proteins like Rab11 family interacting proteins (FIPs).
Purpose of the Study:
- To summarize recent findings on the roles and regulation of the FIP3 and Rab11 complex.
- To describe methods for analyzing membrane and cytoskeleton dynamics during cell division abscission.
Main Methods:
- Review of recent literature on Rab11-endosomes, FIP3, and cytokinesis.
- Description of novel methods for analyzing membrane and cytoskeleton dynamics.
Main Results:
- FIP3 is key in targeting Rab11-endosomes during mitosis.
- The Rab11-FIP3 complex is central to regulating endosome trafficking in cell division.
- Advanced methods allow detailed analysis of membrane and cytoskeletal rearrangements.
Conclusions:
- The Rab11-FIP3 complex is a critical regulator of cytokinesis and abscission.
- New analytical techniques enhance understanding of the molecular mechanisms governing cell division.

02:15The Contractile Ring
7.5K
Contractile rings are composed of microfilaments and are responsible for separating the daughter cells during cytokinesis. Contractile ring assembly proceeds along with other cell cycle events; however, very few mechanistic details are known about the timing and coordination of the contractile rings with the cell cycle.
A small GTPase, RhoA, controls the function and assembly of the contractile ring. RhoA belongs to the Ras superfamily of proteins. The activation of formins by RhoA promotes...

5.4K
Rab proteins constitute the largest family of monomeric GTPases, of which 70 members are present in humans. Rab proteins and their effectors regulate consecutive stages of vesicle transport such as vesicle transport, docking, and fusion to the correct recipient membrane.
Rab proteins switch between a cytosolic, GDP-bound inactive state and a membrane-anchored, GTP-bound active state. By themselves, Rabs show slow rates of GDP/GTP exchange and GTP hydrolysis. Thus, Rab proteins are considered...

01:25Rab Cascades
3.8K
Rab GTPases act in a regulated cascade during membrane fusion, helping the lipid bilayers mix. The Rab family of proteins are active when bound to GTP, and inactive when bound to GDP. Hence, they act as guanine nucleotide-dependent molecular switches. Rab-GTP recognizes and binds to long or short-range tethering proteins to capture the target vesicle. These tethers coordinate with SNAREs on the vesicle and the target membrane to assemble the trans SNARE complex that locks the mixing bilayers.

01:21Cell Polarization by Rho Proteins
4.1K
Cell polarity is the asymmetric distribution of cellular and membrane components, making one side of the cell different from the other. This polarity is essential to many processes such as embryogenesis, axon migration, glucose transport across epithelial cells, and directional cell migration. A migrating cell responds to intracellular or extracellular signals via molecular cascades that reorganize the actin cytoskeleton to establish this polarity. In these cells, the Rho family proteins Cdc42,...

Positive regulators allow a cell to advance through cell cycle checkpoints. Negative regulators have an equally important role as they terminate a cell’s progression through the cell cycle—or pause it—until the cell meets specific criteria.

3.4K
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...
