Protein Modules in Cellular Signalling

Dynamic stability of cells is a function of co-ordination and counterbalance between intracellular signalling events. Therefore, the knowledge of those molecules which form signalling cascades or signalling modules is of prime importance in understanding living processes. Signalling proteins, the component members of different cascades, are the focus of intense interest. Protein phosphorylation dephosphorylation is the prevalent mechanism by which signalling molecules transduce their signals.
