Polarized microscopy technique shows new details of how proteins are arranged
Date:4/17/2011

ctures into a high-resolution map of the entire nuclear pore complex."

Eventually, the scientists say their technique could go even further. Because the proteins' fluorescence can be measured while the cells are still alive, it could give scientists new insights into how protein complexes react to varying environmental conditions, and how their configurations change over time.

"What happens when other proteins pass through the nuclear pore? Does the orientation of the nucleoporins change? With this technique, can find out not only what the pore looks like when it's sitting still, but what happens to it when it's active," Simon says. Their first characterization of the dynamics of the nuclear pore proteins was published recently in The Biophysical Journal.
