For years, social media posts have insisted that this animation represents an action that takes place in the brain.
The motions of muscles as well as much smaller intracellular cargoes are driven by molecular motors that move unidirectionally along protein polymers . […] Muscle myosin, whose study dates back to 1864, has served as a model system for understanding motility for decades. Kinesin, discovered […] in 1985, is a relative newcomer by comparison.
Both myosin and kinesin have identical pairs of molecules that “latch” onto different types of cellular structures. In kinesin they move overdistances with coordinated steps. In myosin, which is most famous for the processes that drive muscle contractions, those latching molecules operate independently of each other, and the system produces more of a single tug than a coordinated strut.
While scientists have not produced actual images or videos of such molecules with the clarity of this visualization, increasingly precise microscopic techniques and tools have allowed a detailed characterizations and direct observations of their movement. A groundbreakingin 1993 detailed for the first time the nature of a kinesin movement — if you’re wondering, each step is just about eight nanometers long.
While some posts assert that this animation represents an action that takes place in the brain, the creator says that it — and the larger video it is part of — actually “takes the viewer through many of the inner workings of a leukocyte showing many of the cellular structures and organelles along the way.” While kinesinsin transporting numerous important chemicals within neurons, that is not a process that would be happening in a white blood cell.
Because this picture shows an artist’s visualization of a kinesin protein in a white blood cell and not a myosin protein in a neuron, and it is not an actual video but a representation, we rate the claim that this picture is a visual representation of “happiness” as false.
