In eukaryotes many vital cellular functions like metabolism,
motility, secretion, growth, differentiation are ultimately
regulated by protein phosphorylation/dephosphorylation.
Extracellular signals which trigger thesechanges control
protein kinases and protein phosphatases. It is the aim of
this volume to unveil signal networks which connect
extracellular signals via second messengers with chages of
the phosphorylation state of target proteins.
