Actin (3 of 3) (IMAGE) Rice University Caption An electron microscope image shows actin filaments held together in parallel or branching arrangements by CaMKII proteins in a neuron. Simulations and experiments carried out at Rice University, the University of Houston and the University of Texas Health Science Center at Houston showed the spacing between adjacent CaMKII particles in the complexes is nearly fixed at 36 nanometers. The scale bar is 100 nanometers. The image was made in the Structural Biology Imaging Center at McGovern Medical School at UTHealth.
