Team Discovers how Tiny parts of Cells Stay Organized, Adding New Insights for Blocking Cancer Growth
City of Hope researchers have modeled the interaction between two proteins, paxillin and focal adhesion kinase (FAK), offering potential new avenues for cancer therapies. The team focused on how these proteins,both critical in cell structure and movement,bind together.
Paxillin, known for its disordered structure, presented a challenge. The team discovered that when paxillin and the FAK C-terminal targeting domain (FAT) connect at a specific site, they contract to fit a confined space. Despite this size reduction, they maintain flexibility within the broader focal adhesion network.
“Our results point to a novel mechanism of protein interaction that is less studied in the literature and indicates the possibility of such mechanisms to be applicable to other disordered proteins,” said Dr. Salgia.
Salgia added that the study has broad implications for disordered proteins in general.
Typically, such protein interactions are hard to target with drugs as of the lack of a clear binding site. However, by capturing the dynamics of paxillin and FAT, the researchers developed a model that coudl aid in identifying drug targets.
The team combined spectroscopy, a technique related to MRI, with dynamic simulations to visualize how paxillin binds to FAT. They then created a 3D computer model to illustrate the interaction.
“The combination of all these methods enabled us to accurately characterize the structural features of the paxillin-FAK interaction more than any single method on its own,” said Dr. Supriyo Bhattacharya, assistant research professor at City of Hope.
What’s next
The team’s model could help other researchers identify a moving target for drug development.
