Researchers catch ion channels in their opening act
Date:7/10/2008

the movement of the voltage sensor during channel opening, Posson measured distances from several different vantage points on the protein.

"It's a lot like dispatching a team of molecular surveyors that stand at specific positions on the surface of a protein and collect distances from point A to point B," Posson said. "With enough measurements, the surveyors can build a map of the three dimensional shape of the protein." Posson discovered that the largest distances traversed by the sensor were about two to three times smaller than what was predicted by the paddle model. It showed that the sensor moves by only a small amount to allow the flow of ions.

"We are seeing a clear result that the movement of the sensor isn't super teeny, and isn't super huge," Posson said. The measurements challenge models that predicted large movements of the protein segments, such as the paddle model. The findings also refute models that have a near zero movement of the sensor region. "It's a small piece to the puzzle of how the voltage sensor moves" Selvin said.
