|Proteins Building a Membrane Tube (.mpg, 5.5M)|
|A variety of structures, including membrane tubes, are required to organize the many functions of living cells. The movie shows BAR domain proteins (shown in red, green, blue and yellow) sculpting a membrane (shown in grey) into a tube. The "tubulation" process occurs over a period of about 200,000 nanoseconds (ns).|
|Protein Bending a Cellular Membrane (.wmv, 5.9M)|
|Membranes in cells display many geometries: flat, curved, or even bubbles. Some of these structures are constructed by proteins within the membranes. The movie shows a photosynthetic light-harvesting protein (in blue, green, red) bending a membrane (in purple and yellow) into a curved shape (bronze area shows curve).|
