Abstract:
Advances in techniques for the study of protein-protein interactions have dramatically improved our understanding of the interactome. However, we know little about the dynamics of this complex system. To better understand the dynamics of the interactome, it is important to consider what happens when single proteins are perturbed. Changes in protein abundance and post-translational modification can function as switches in the interactome, affecting protein-complex assembly and function. Changes in protein sequence or a dramatic increase in abundance might cause a promiscuous gain of interactions. These effects are not identical for all proteins and will differ depending on the number and type of interaction partners that a protein has.

Protein Dynamics in Living Cells
Fluorescent recovery after photobleaching (FRAP) is a fluorescent-protein-based detection technique used to quantify protein movement rates within the cell. This method exposes a small portion of the cell to an intense laser beam. The laser beam causes permanent photobleaching of the fluorophore-tagged proteins in the exposed region. As the bleached...
