Proteins in Motion: Mapping the Landscape of Structure

Understanding protein motion—not just structure—is key to revealing function. In a recent Structural Dynamics study, Joseph I. J. Ellaway, Stephen Anyango, Sreenath Nair, Hossam A. Zaki, Nurul Nadzirin, Harold R. Powell, Aleksandras Gutmanas, Mihaly Varadi, and Sameer Velankar introduce a novel approach to identifying distinct protein conformational states across the Protein Data Bank.

By integrating experimental data with advanced computational clustering, their method captures how proteins shift between biologically important shapes—moving beyond static models toward a more dynamic view of structure. This work opens new avenues for understanding disease mechanisms and advancing drug discovery.

Join Us in Calgary for the 27th IUCr Congress & General Assembly

Congress Homepage

We’re pleased to share that the early registration deadline for IUCr2026 has been extended to May 5.

Early Registration Extended to May 5!

This extension is intended to give participants additional time to finalize plans, particularly as abstract notifications—both oral and poster—continue to be released. We encourage all attendees to take advantage of the reduced early registration rates while they are still available.

IUCr2026 will bring together the global crystallographic community for a dynamic, in-person gathering in Calgary, Canada, from August 11–18, 2026.

The Congress will feature a robust scientific program including 140 microsymposia, keynote lectures, workshops, and poster sessions, showcasing the latest advances across structural science. With contributions from researchers around the world, the program reflects the breadth and impact of crystallography—from fundamental discoveries to applied and interdisciplinary innovation.

Beyond the scientific sessions, IUCr2026 offers valuable opportunities to connect, collaborate, and engage with colleagues at all career stages. Whether you are presenting your work, exploring new research areas, or building professional relationships, the Congress is designed to foster meaningful exchange across the community.
