Title:

Skelemin Association with AlphaIIbBeta3 Integrin: A Structural Model.

Journal:

Biochemistry. 2014 Sep 15.

Abstract:

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.
