Disease-Causing Mutation in Motion (image) Society for Neuroscience Share Print E-Mail Caption Cells with a mutant form of the protein mitofusin 2 contain mitochondria that are smaller and move more slowly than those with normal proteins. This graph shows how much more normal mitochondria move over time (top graph) compared with how little mitochondria with mutated proteins travel (bottom graph).
