Member of a kinase network in which "upstream" kinases activate "downstream" kinases that, in response to phosphorylation, translocate to the nucleus and activate transcription factors.
Note: These include the extracellular regulated kinases (Erk), stress-activated protein kinase (SAPK or p38), and the kinase of the c-jun oncoprotein (JNK).
