Disruption of the integrin alphaLbeta2 transmembrane domain interface by beta2 Thr-686 mutation activates alphaLbeta2 and promotes micro-clustering of the alphaL subunits.

Abstract excerpt

Integrins are type I heterodimeric cell adhesion molecules that mediate a wide array of biological processes. Integrin bidirectional signaling allows communication between the cell interior with its microenvironment. The integrin transmembrane domains (TMs) are the transducers of activation signal that is relayed from the cytoplasmic domains to the distal ligand binding site located in the ectodomain of the...
