The first attempts to establish the set of proteins that participate directly ('bona fide' adhesome components) or affect indirectly ('associated' adhesome components) cell adhesion were based on mining of the primary research literature, and resulted in approximately 200 protein in either integrin or cadherin adhesomes.
Cell adhesion molecules (CAMs) are a subset of cell surface proteins [1] that are involved in the binding of cells with other cells or with the extracellular matrix (ECM), in a process called cell adhesion. [2] In essence, CAMs help cells stick to each other and to their surroundings.
Schematic of cell adhesion. Cell adhesion is the process by which cells interact and attach to neighbouring cells through specialised molecules of the cell surface. This process can occur either through direct contact between cell surfaces such as cell junctions or indirect interaction, where cells attach to surrounding extracellular matrix, a gel-like structure containing molecules released ...
The immunoglobulin superfamily (IgSF) is a large protein superfamily of cell surface and soluble proteins that are involved in the recognition, binding, or adhesion processes of cells. Molecules are categorized as members of this superfamily based on shared structural features with immunoglobulins (also known as antibodies); they all possess a ...
One characteristic of adhesion GPCRs is their extended extracellular region. This region is modular in nature, often possessing a variety of structurally defined protein domains and a membrane proximal GAIN domain. In the aptly named Very Large G protein-coupled Receptor 1 VLGR1 the
Regulation proteins – regulate membrane vesicle targeting. Transmembrane proteins – including junctional adhesion molecule, occludin, and claudin. It is believed that claudin is the protein molecule responsible for the selective permeability between epithelial layers.
The loss of the cell adhesion molecules, E cadherins, is causally involved in the formation of epithelial types of cancers such as carcinomas. The changes in any types of cadherin expression may not only control tumor cell adhesion but also may affect signal transduction leading to the cancer cells growing uncontrollably. [23]
These short amino acid sequences are the minimum motif of a larger protein that is necessary for binding to a cell surface receptor that drives cell adhesion. [40] The majority (89%) of published studies on biomaterials functionalized with cell adhesive peptides use RGD, whereas IKVAV and YIGSR are used in 6%, and 4% of those studies ...
