Phosphorylation Modulated Networks of the Cell
At any time, in any cell, multiple types of molecular networks are concurrently active. These networks are neither static nor are they independent. Thousands of proteins are simultaneously busy in our cells; some occur in great numbers, others in trifling quantities – which does not necessarily mean that they are less important. Perturbations of the cell induce coordinated changes in multiple networks and one of the predominant open questions in systems biology is how, exactly this coordination is achieved. In other words: how do cells process information.
