Cell Adhesion & Migration
|October 16, 2010
Summary
Cell adhesion molecules (CAMs) regulate cell signaling beyond adhesion. Their interactions, influenced by proteases and membrane rafts, dictate diverse cellular functions.
Area of Science:
- Cell Biology
- Molecular Biology
- Biochemistry
Background:
- Cell adhesion molecules (CAMs) traditionally mediate cell-cell and cell-extracellular matrix adhesion.
- Emerging research reveals CAMs significantly influence intracellular signaling pathways, including receptor tyrosine kinases.
- CAMs also function as substrates for proteases, generating signaling fragments.
Purpose of the Study:
- To explore the multifaceted roles of CAMs in cellular processes.
- To elucidate how CAMs modulate signaling pathways and cell behavior.
- To understand the impact of protease-cleavage and membrane rafts on CAM function.
Main Methods:
- Review of existing literature on CAMs, receptor tyrosine kinases, and signaling pathways.
- Analysis of studies investigating CAMs as protease substrates.
- Examination of the role of membrane rafts in modulating CAM-mediated signaling.
Main Results:
- CAMs modulate receptor tyrosine kinase activation, impacting cell survival, migration, and extension.
- Proteolytic cleavage of CAMs generates diffusible signaling fragments.
- Membrane rafts dynamically regulate the co-localization of signaling molecules, influencing pathway activation.
Conclusions:
- The functions of CAMs are context-dependent, influenced by cell history and molecular repertoire.
- CAMs exhibit diverse signaling capabilities extending beyond simple adhesion.
- Understanding CAMs requires considering their interactions within the complex cellular microenvironment.

Cell Adhesion Molecules - Types and Functions
Cell adhesion molecules (CAMs) are pivotal to multicellularity and the coordinated functioning of tissues and organ systems. They enable physical interactions between cells and provide mechanical strength to tissues. They also function as receptors for signal transmission across the plasma membrane. The CAMs are broadly classified into four families - integrins, cadherins, selectins, and immunoglobulin-like CAMs (IgCAMs).

Immunoglobulin-like Cell Adhesion Molecules
Immunoglobulin-like cell adhesion molecules or Ig-CAMs are a versatile group of cell surface glycoproteins belonging to the immunoglobulin protein superfamily. Ig-CAMs possess the characteristic immunoglobulin protein domains and other domains such as the fibronectin type III domain. The Ig domains are glycosylated to varying degrees in different Ig-CAMs.
Ig-CAMs exhibit either homophilic binding (to other Ig-CAMs) or heterophilic binding (to other ligands such as integrins). While most Ig-CAMs...

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 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.
