The mitogen-activated protein kinases (MAPKs) ERK2/MAPK1 and ERK1/MAPK3 (hereafter referred to collectively as ERK1/2) are activated by phosphorylation in a canonical Raf MEK ERK kinase cascade in response to most growth factors and cytokines, and ERK1/2 phosphorylate more than 150 cytosolic and nuclear substrates [5], [6].

Kinases7
These phosphatases inactivate their target kinases by dephosphorylating both the phosphoserine/threonine and phosphotyrosine residues. (wikipedia.org)
Although the importance of kinases in this process has long been recognized, an appreciation for the complex and fundamental role of phosphatases is more recent. (rupress.org)
Through extensive biochemical and genetic analysis, we now know that pathways are not simply switched on with kinases and off with phosphatases. (rupress.org)
Furthermore, kinases and phosphatases may work together to modulate the strength of a signal. (rupress.org)
Adding further complexity to this picture is the fact that both kinases and phosphatases can function in signaling networks where multiple kinases and phosphatases contribute to the outcome of a pathway. (rupress.org)
