ERK, ERK signaling: Click to Expand ⟱
Source:
Type:
MAPK3 (ERK1)
ERK proteins are kinases that activate other proteins by adding a phosphate group. An overactivation of these proteins causes the cell cycle to stop.
The extracellular signal-regulated kinase (ERK) signaling pathway is a crucial component of the mitogen-activated protein kinase (MAPK) signaling cascade, which plays a significant role in regulating various cellular processes, including proliferation, differentiation, and survival. high levels of phosphorylated ERK (p-ERK) in tumor samples may indicate active ERK signaling and could correlate with aggressive tumor behavior

EEk singaling is frequently activated and is often associated with aggressive tumor behavior, treatment resistance, and poor outcomes.
