Erk activation

WebThe activation of ERK turns out to be paradoxical, since it is a kinase not directly involved in the innate immune response; nevertheless, it gets activated by treatments with picograms of the monomeric VCC. Activated ERK is indicative of a survival response, since it occurs here under the exposure of a restricted concentration of the monomeric ... The signal that starts the MAPK/ERK pathway is the binding of extracellular mitogen to a cell surface receptor. This allows a Ras protein (a Small GTPase) to swap a GDP molecule for a GTP molecule, flipping the "on/off switch" of the pathway. The Ras protein can then activate MAP3K (e.g., Raf), which activates MAP2K, which activates MAPK. Finally, MAPK can activate a transcription factor, …
