Cell's 'Power House' with Mutated Protein (1 of 2) (video) Society for Neuroscience Share Print E-Mail Loading video... Caption This pair of time-lapse movies show mitochondria moving along nerve cell fibers. In the first clip, mitochondria with normal mitofusin proteins move quickly along the fiber. In this second clip, mitochondria with a mutant form of mitofusin 2 are smaller and move slowly. This abnormal movement is thought to be the basis for the neurodegenerative disease Charcot-Marie-Tooth type 2A. Credit Courtesy, with permission: Misko et al. The Journal of Neuroscience 2010.
