Decrypting Integrins by Mixed-Solvent Molecular Dynamics Simulations.

ABSTRACT: Integrins are a family of α/β heterodimeric cell surface adhesion receptors which are capable of transmitting signals bidirectionally across membranes. They are known for their therapeutic potential in a wide range of diseases. However, the development of integrin-targeting medications has been impacted by unexpected downstream effects including unwanted agonist-like effects. Allosteric modulation of integrins is a promising approach to potentially overcome these limitations. Applying mixed-solvent molecular dynamics (MD) simulations to integrins, the current study uncovers hitherto unknown allosteric sites within the integrin α I domains of LFA-1 (α_Lβ₂; CD11a/CD18), VLA-1 (α₁β₁; CD49a/CD29), and Mac-1 (α_Mβ₂, CD11b/CD18).
