Protein interactions animation. Clip 5 of 10. This clip forms part of an animation sequence showing protein interactions within a dividing cell. This clip, which includes labels, shows an actin-myosin bundle forming part of the contractile ring at the periphery of the cell. Proteins are moving through the surrounding cytoplasm, including those that activate the contractile ring. This contraction is initiated by a wave of calcium ions (small, fast-moving objects), shown towards the end of the clip. The full sequence of ten clips shows the interaction between the protein calmodulin (CaM, calcium-modulated protein), calcium ions, the MLCK (myosin light-chain kinase) protein, and the actin-myosin bundles of the cell's cytoskeleton, resulting in contraction of the membrane and cell division. For the entire sequence, see clips K003/3847 to K003/3838. For the same sequence as an anaglyph 3D animation, see clips K003/4492 to K003/4483.
