Cell Motility and the Cytoskeleton
|June 23, 2009
Summary
Connexins (Cx) proteins form gap junctions and interact with cellular components to create a Nexus complex. These interactions regulate cell communication and Cx functions, including cell motility.
Area of Science:
- Cell Biology
- Molecular Biology
- Biochemistry
Background:
- Connexins (Cx) are transmembrane proteins forming gap junctions for intercellular communication.
- Cx proteins interact with various cellular components, forming a multiprotein complex called the Nexus.
- Emerging evidence suggests Cx proteins have channel-independent functions beyond cell communication.
Purpose of the Study:
- To review current knowledge on connexin interactions with cytoskeletal proteins.
- To highlight the role of these interactions in cellular motility.
- To explore the channel-independent functions of connexins.
Main Methods:
- Literature review of recent scientific reports and studies.
- Analysis of protein-protein interactions involving connexins.
- Summarization of findings on connexin roles in cellular processes.
Main Results:
- Connexin interactions with cytoskeletal proteins are crucial for their localization and function.
- The Nexus complex, involving Cxs and other proteins, influences gap junction communication.
- Connexins exhibit channel-independent functions, impacting cell migration, polarization, and growth control.
Conclusions:
- Connexin interactions with the cytoskeleton are vital for regulating cellular motility.
- The Nexus complex plays a significant role in both channel-dependent and -independent connexin functions.
- Further research into Cx channel-independent roles is warranted.

01:32Cytoskeletal Coordination in Cell Migration
A migrating cell changes its shape during the cyclic events of attachment and detachment from the substratum and repositions the cell organelles correspondingly. These complex events are orchestrated by the dynamic cytoskeletal network comprising actin filaments, intermediate filaments, and microtubules. Cytoskeletal crosstalk — the direct and indirect communication between the different components — is crucial for this coordination. Direct communication involves various linker proteins that...
01:16Cell Motility through Blebbing
Blebs are a type of membrane protrusion formed by the internal hydrostatic pressure of the cytoplasm. Blebs are observed in several cell types, including fibroblasts, immune cells, and single-celled organisms like the amoeba. The primary function of blebs is cell locomotion and apoptosis, but they are also found during necrosis and cell division. The life cycle of a bleb comprises an initiation phase followed by the expansion and retraction phases.

01:13Actin Polymerization and Cell Motility
Actin is a family of globular proteins that are highly abundant in eukaryotic cells. It makes up approximately 1-5% of total cell protein concentration. Actin monomers polymerize to form a complex network of polarized filaments, the actin cytoskeleton, that plays a crucial role in many cellular processes, including cell motility, division, endocytosis, and metastasis of cancer cells.
Actin cytoskeleton dynamics can produce pushing, pulling, and resistance forces that help the cell to migrate.

01:24Microtubules in Cell Motility
Microtubules are thick hollow cylindrical proteins that help form the cytoskeleton. Microtubules have varied roles in the cell. These filaments help form cellular appendages like cilia and flagella, which are responsible for locomotion. The cilia arise from basal bodies, separated from the main body by a membrane-like structure forming the transition zone. This zone is the gate for the entry of lipids and proteins, creating a unique composition of lipids and proteins in the ciliary membrane and...

01:13Cell-matrix's Response to Mechanical Forces
In animal cells, the extracellular matrix allows cells within tissues to withstand external stresses and transmits signals from the outside of the cell to the inside. The extracellular matrix is extensive, and its composition varies between different types of tissues. For example, the reticular fibers and ground substance make up the ECM in loose connective tissue, while collagen and bone minerals make up the ECM of bone tissue.
