Integrin structure and function

NettetThe initial description of α 4 β 1 integrin dates back 30 years, when in 1987, based on biochemical studies, Martin Hemler and co-workers [ 1] described it as a distinct Mr 150 000/130 000 α 4 β heterodimer and thus a new member of the VLA-protein family on human T lymphoblastoid cells and peripheral blood T cells. NettetX-ray crystallographic structures of the extracellular domains of αVβ3 have provided insights into the integrin structure-function relationship (Xiong et al., 2002; Van Agthoven et al., 2014). Disintegrins containing RGD or KGD motifs have been reported as unique and potentially useful tools to investigate integrin-ligand interactions.

Nettetmotifs that function in integrin binding were later found in many other extracellular matrix proteins (3). All known RGD receptors on cell surfaces belong to the integrin family. Eight vertebrate integrins recognize an RGD motif in ligands (4, 5). In Del-1, this RGD motif is responsible for mediating the attachment of endothe- NettetIntegrins are attractive drug targets as their antagonism can block several steps in disease progression or maintenance. Integrin inhibitors can block the proliferation, migration, or tissue localization of inflammatory, angiogenic, and tumor cells, as well as signaling and gene expression contributing to disease.
