    4. Differential phosphatidylinositol 4,5-diphosphate binding of vinculin isoforms promotes quasi-equivalent dimerization. PMID: 27503891
    5. Study used an all-heavy-atom structure-based model to study vinculin activation by talin in a high-tension context mechanically driven by F-actin, showed that vinculin activation may proceed from an intermediate state stabilized by partial talin-vinculin association.

Another module involves paxillin and FAK, which soft substrates also destabilize, but independently of vinculin head-tail interaction. This multi-modularity may be key to allow a versatile response to complex biomechanical cues. PMID: 27169142
