Insights

Cell-cell adhesion dynamics are crucial for development and metastasis. Rho-family GTPases (RhoA, Rac1, Cdc42) are key regulators, with signaling pathways between cadherins and these GTPases now being clarified.

Area of Science:

  • Cell Biology
  • Molecular Biology
  • Developmental Biology

Background:

  • Cell-cell adhesions are dynamic structures essential for multicellular organism development and disease processes like tumor metastasis.
  • Cadherin-mediated adhesion is a primary mechanism for cell-cell adhesion.
  • Rho-family GTPases (including RhoA, Rac1, and Cdc42) are increasingly recognized as critical regulators of cellular processes.

Purpose of the Study:

  • To elucidate the role of Rho-family GTPases in regulating cadherin-mediated cell-cell adhesion.
  • To understand the signal transduction pathways connecting cadherins and Rho GTPases.

Main Methods:

  • Identification and characterization of regulators and effectors of Rho GTPases.
  • Analysis of signaling pathways involved in cadherin-mediated adhesion.

Main Results:

  • Rho-family GTPases (RhoA, Rac1, Cdc42) are identified as key regulators of cadherin-mediated cell-cell adhesion.
  • Signal transduction pathways linking cadherins to Rho GTPases and vice versa are beginning to be elucidated.

Conclusions:

  • Rho-family GTPases play a central role in modulating cell-cell adhesion dynamics.
  • Understanding these pathways provides insights into tissue development and tumor metastasis.

Rab Proteins01:14

Rab Proteins

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...
Rab Cascades01:25

Rab Cascades

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.
Small GTPases - Ras and Rho01:24

Small GTPases - Ras and Rho

Ras and Rho are small monomeric GTPases that act downstream of receptor tyrosine kinase (RTK) and regulate various cellular processes. These GTPases switch between active and inactive states by binding to guanine nucleotides.

Structure of Cadherins01:25

Structure of Cadherins

The cadherins were one of the first cell adhesion molecules discovered; the term “cadherins”   is based on their calcium-dependent adhering properties. The first cadherins discovered on the epithelial, neuronal, and placental cells were named E-cadherin, P-cadherin, and N-cadherin, respectively. These classical cadherins share sequence and structural similarities. Other cadherins, including those involved in cell signaling, are grouped into non-classical cadherins. This diversity of cadherins...
Catenins01:23

Catenins

Catenins are characterized by multiple binding domains and dynamic structures that allow them to function as linker proteins in cell junction complexes. All catenins, except α-catenin, contain a characteristic protein sequence called the armadillo repeat and are therefore also called armadillo proteins.
Catenins in Cell Junctions
Catenins bind to cell adhesion molecules such as cadherins and link them to different cytoskeletal proteins depending on the type of cell junction. At the adherens...
Cadherins in Tissue Organization01:19

Cadherins in Tissue Organization

The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.
