Skelemin Association with AlphaIIbBeta3 Integrin: A Structural Model.
Biochemistry. 2014 Sep 15.
Over the last two decades, our knowledge concerning intracellular events that regulate integrin's affinity to their soluble ligands has significantly improved. However, the mechanism of adhesion-induced integrin clustering and development of focal complexes, which could further mature to form focal adhesions, still remains under-investigated. Here we present a structural model of tandem IgC2 domains of skelemin in complex with the cytoplasmic tails of integrin alphaIIbbeta3. The model is generated based upon NMR data and this tertiary assembly illuminates a potential link between the essential cell adhesion receptors and myosin filaments. This connection may serve as a basis for generating the mechanical forces necessary for cell migration and remodeling.
