Abstract
It would be the dream of many experimental scientists in cell biology to be able to follow the life of a protein molecule over time, to watch its encounters with other proteins, to record its conformational fluctuations, and from that data to understand its functionality. Indeed, technology is now at hand to detect the signal of a single molecule in a live cell context. In particular, researchers have been employing single molecule tracking to recover the forces that act on biomolecules: active transport can be discriminated from free or confined diffusion, and nanoscopic details within the molecular paths can be investigated. In the first part of this chapter, we provide an overview over typical diffusion models for biomolecular motion. Yet, experiment, data analysis, and interpretation are not that simple: trajectories are frequently too short, the data are too noisy, and only a vanishingly small fraction of proteins is actually visible. In the second part of this chapter, we therefore delineate how diffusion models can be implemented for data analysis. As a showcase, we discuss recent single molecule data obtained on Lck, an important kinase in T cell signaling.
