Unprecedented Detail: Microscope Captures Motor Proteins with Power.
Two independent teams have used a super-resolution tool called MINFLUX to study molecular motors called kinesins in near-real time at physiologically relevant concentrations of ATP. The teams were able to track the protein in 3D and capture side-stepping, stalling, and hops from one microtubule to another. The new technology could open multiple research avenues, especially if it allows researchers to track several proteins or several sites in proteins at once.
