Insights

Cadherin cell-cell contacts activate signaling pathways like Rho GTPases and Wnt signaling. These downstream signals are specific to the cadherin type and cell context.

Area of Science:

  • Cell Biology
  • Molecular Signaling
  • Biochemistry

Background:

  • Cadherin-mediated cell-cell contact is crucial for tissue integrity and cellular communication.
  • Recent research highlights the involvement of cadherins in diverse intracellular signaling pathways.

Purpose of the Study:

  • To review and synthesize recent findings on signaling pathways activated by cadherin-mediated cell-cell contacts.
  • To emphasize the specificity of downstream signaling in relation to cadherin type and cellular context.

Main Methods:

  • Literature review of recent studies on cadherin signaling.
  • Analysis of molecular mechanisms linking cadherins to downstream effectors.

Main Results:

  • Cadherin contacts activate Rho family GTPases, influencing cell adhesion and migration.
  • Cadherin interactions modulate beta-catenin availability for Wnt signaling.
  • Cadherins participate in receptor tyrosine kinase signaling pathways.

Conclusions:

  • Downstream signaling initiated by cadherin-mediated contacts is highly specific.
  • Signal outcomes depend on both the specific cadherin involved and the cellular environment.

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...

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.

Intracellular Signaling Affects Focal Adhesions01:17

Intracellular Signaling Affects Focal Adhesions

Integrins act both as extracellular input receivers and as intracellular processing activators. As their name suggests, integrins are entirely integrated into the membrane structure. Their hydrophobic membrane-spanning regions interact with the phospholipid bilayer's hydrophobic region. These membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors. They activate intracellular response cascades when their effectors are bound and active.

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...
Adherens Junctions01:24

Adherens Junctions

Strong contact points between adjacent cells anchor them to each other, forming tissues. Such anchoring junctions are of two types –  adherens junctions and desmosomes. Adherens junctions are abundant in tissues such as  epithelium and endothelium, forming a continuous zone of adhesion called the adhesion belt. In other tissues, such as  heart muscle, they appear as clusters, linking the cells to produce coordinated heart muscle contraction.
Adherens Junctions are Dynamic

Assembly of Signaling Complexes01:30

Assembly 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.
