A cell’s private life revealed
The Yale University team was able to visualize the so-called “BK” channel protein by using single-particle reconstruction. In this technique, individual protein molecules are imaged in an electron microscope, and information from thousands of images is combined to produce a three-dimensional map of the protein structure. This was the first time this reconstruction technique was extended to proteins embedded in membranes.
