Protein interactions, cell membrane. Clip 6 of 7. Animation showing proteins interacting on a cell membrane, some embedded and some free-floating. Some membrane proteins (receptors) bind to and detect free-floating proteins. Others form rafts, such as the ones in the background here. These proteins (found on white blood cells) include ICAM (tall), toll-like receptors (curved, hook-like dimer), and CD4. The smaller membrane molecules (foreground) are sugars. This clip is part of a sequence showing cellular protein interactions. For the entire sequence, see clips K003/3837 to K003/3831.
