Protein interactions animation. Clip 2 of 10. This clip forms part of an animation sequence showing protein interactions within a dividing cell. This clip, which includes labels, shows small sugars and rafts of proteins on the outside of the cell membrane. Towards the end of the clip, ions emerge from a potassium ion channel and the viewpoint swings down, with the clip ending with a view of the ion channel. 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. |
