Integrins are heterodimeric transmembrane receptors that mediate cell-adhesion. 1 With their extracellular head region, most integrins bind extracellular matrix (ECM) glycoproteins such as laminins and collagens in basement membranes or connective tissue components like fibronectin.

The integrins are a superfamily of cell adhesion receptors that bind to extracellular matrix ligands, cell-surface ligands, and soluble ligands. They are transmembrane αβ heterodimers and at least 18 α and eight β subunits are known in humans, generating 24 heterodimers.

Oct 7, 2020 · Integrins are a family of ubiquitous αβ heterodimeric receptors that interact with numerous ligands in physiology and disease. Integrins play a key role in cell proliferation, tissue...

Integrins are cell adhesion receptors that are evolutionary old and that play important roles during developmental and pathological processes. The integrin family is composed of 24 αβ heterodimeric members that mediate the attachment of cells to the ...

These constitute a large family of homologous transmembrane, cell-matrix adhesion receptors. In blood cells, as we have seen, integrins also serve as cell-cell adhesion molecules, helping the cells bind to other cells, as well as to the extracellular matrix.

Integrins are large, membrane-spanning, heterodimeric proteins that are essential for a metazoan existence. All members of the integrin family adopt a shape that resembles a large “head” on two “legs,” with the head containing the sites for ligand binding and subunit association.

The integrin family is composed of 24 alphabeta heterodimeric members that mediate the attachment of cells to the extracellular matrix (ECM) but that also take part in specialized cell-cell interactions. Only a subset of integrins (8 out of 24) recognizes the RGD sequence in …

Aug 20, 2009 · The integrin family is composed of 24 αβ heterodimeric members that mediate the attachment of cells to the extracellular matrix (ECM) but that also take part in specialized cell-cell interactions. Only a subset of integrins (8 out of 24) recognizes the RGD sequence in …

Integrins are heterodimeric cell adhesion molecules that link the extracellular matrix to the cytoskeleton. The integrin family in man comprises 24 members, which are the result of different combinations of 1 of 18 alpha- and 1 of 8 beta-subunits.

Integrins exist as heterodimers composed of noncovalently bound α and β subunits. The α subunits have three or four divalent cation-binding regions in the extracellular domain, and in some, two disulfide-linked heavy and light chains constitute a single subunit.
