Summary
Cadherins, crucial for cell adhesion, are now understood through their molecular links to the actin cytoskeleton. New findings reveal how signals regulate cadherin function and their roles in cell signaling and differentiation.
Area of Science:
- Cell biology
- Molecular biology
- Biochemistry
Background:
- Cadherins are key cell-cell adhesion molecules.
- They connect to the actin cytoskeleton through associated proteins.
Purpose of the Study:
- To explain cadherin behavior at a molecular level.
- To investigate signals regulating cadherin-associated complexes.
- To explore cadherin cross-adhesion and signaling roles.
Main Methods:
- Molecular analysis of cadherin-associated complexes.
- Investigation of signaling pathways affecting adhesion.
- Studies on cadherin cross-adhesion capabilities.
- Examination of cadherin involvement in cell differentiation.
Main Results:
- Molecular mechanisms underlying cadherin behavior are elucidated.
- Signals modulating cadherin-associated complexes regulate adhesion.
- Evidence suggests different cadherins can cross-adhere.

01:03Anchoring Junctions
Anchoring junctions are multiprotein complexes that help cells connect to other cells and the extracellular matrix. Anchoring junctions are present on the lateral and basal surfaces of cells, providing strong and flexible connections. Focal adhesions are often formed due to cell interactions with the ECM substrata, which initiate signal transduction via kinase cascades and other mechanisms. Together, they provide stability and tissue integrity. There are three types of anchoring junctions:...
01:25Structure 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...
01:23Catenins
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.

01:24Adherens 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.

01:19Cadherins 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.

01:26Tension Response at Adherens Junctions
The adherens junctions that anchor cells together are multi-protein complexes that dynamically adapt to mechanical stimuli such as tensile forces and shear stress. Mechanosensory proteins in these junctions can sense such mechanical stimuli and undergo a shift in their conformation, resulting in an altered function — a process called mechanotransduction.
