Indeed, when a detailed biochemical analysis of the mussel footprints was performed, biomolecular signatures
of the adhesive proteins were found on all the control materials but not on the Wyss» slippery surfaces.
Thanks to an incredibly strong matrix
of adhesive proteins, known as byssal threads, that it extrudes through its two - hinged shell, the mussel is able to anchor itself to almost any surface — even Teflon.

The Rutgers scientists further show that the transcription activator
protein makes two separate, successive sets
of adhesive, Velcro - like interactions with RNA polymerase: one that helps RNA polymerase bind to the DNA helix, and a second set that helps RNA polymerase unwind the DNA helix.
Mussels can grip fast to wet and rough surfaces using an
adhesive protein and tough, plasticky fibres that can repair themselves when a few

Finally, in a collaboration with Frank Jülicher's group at the Max Planck Institute for the Physics
of Complex Systems, we are using these data to develop physical models that will help us understand how local cellular
adhesive, elastic and contractile properties are influenced by PCP
proteins and other molecules, and how they combine to produce specific packing geometries at a global level.
