MAPK
Mitogen-activated protein kinases (MAPK) are a family of protein kinases involved in cell proliferation, cell differentiation, cell movement, and cell death. MAPK signaling cascades are organized hierarchically where: -MAPKs are phosphorylated and activated by MAPK-kinases (MAPKKs), -MAPKKs are phosphorylated and activated by MAPKK-kinases (MAPKKKs). -MAPKKKs are in turn activated by interaction with the family of …
