Summary
Classic cadherins are vital for synapse formation and remodeling in the vertebrate central nervous system. This review explores how cadherins and their partners regulate synaptic architecture and connections through molecular mechanisms.
Area of Science:
- Neuroscience
- Cell Biology
- Molecular Biology
Background:
- Cadherins are Ca2+-dependent homophilic adhesion molecules crucial for synaptic organization.
- Their adhesive strength is modulated by conformational changes, binding partners, and turnover.
- Synaptic architecture and connections are dynamically regulated processes.
Purpose of the Study:
- To review recent findings on cadherins and associated proteins in synaptic architecture.
- To discuss molecular mechanisms of cadherin turnover and its impact on synaptic connections.
Main Methods:
- Literature review of recent studies.
- Analysis of molecular mechanisms regulating cadherin function and turnover.
Main Results:
- Cadherins play a central role in organizing vertebrate central nervous system synapses.
- Association with intracellular proteins and regulation of cadherin turnover impact synaptic adhesion.
- Understanding cadherin dynamics is key to comprehending synaptic remodeling.
Conclusions:
- Cadherins and their partners are critical regulators of synaptic architecture.
- Molecular mechanisms of cadherin turnover significantly influence synaptic connections.
- Further research into cadherin dynamics will illuminate synaptic plasticity and development.

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.

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...
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.

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.

Desmosomes
The term desmosome derives from the Greek words "desmo" and "soma" meaning "adhesion bodies." This structure was first observed during the late 1800s and described as small, dense nodules in the epidermis. Desmosomes are button-like structures that help form an interlinked network of intermediate filaments across the cells. These junctions are essential to hold cells together under mechanical stress and to maintain tissue integrity. Desmosomes are multi-protein complexes comprising desmosomal...
Tension 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.
