Abstract:
Integrins are cell surface receptors for cell adhesion. Integrin-mediated cell adhesion regulates various cellular processes, including cell survival, migration, proliferation, and differentiation. In vivo, ligands for integrins are immobilized within extracellular matrices, insoluble sheet-like or fibrous supramolecular complexes that associate with or surround cells. To better understand the molecular basis of integrin-mediated regulation of cellular behavior in vivo, it is of critical importance to collect information regarding the activities as well as spatial distributions of integrin ligands in situ. This unit describes a protocol for detecting the spatial distribution of the complement of integrin ligands in situ by overlaying soluble recombinant integrins.

Activation of Integrins
In "outside-in signaling," external factors in the extracellular space bind to exposed ligand binding sites on integrins. This causes the inactive protein to undergo a conformational change to become active. Integrins are often clustered on the cell membrane. Repetitive and regularly spaced ligand binding...
