Background
Phospho-ERK1/2 (Thr202/Tyr204) is the hallmark modification for full activation of ERK1/2 kinases. The conserved dual phosphorylation sites Thr202/Tyr204 are specifically modified by upstream MEK kinases. Dual phosphorylation at these residues completely activates ERK1/2 kinase activity, promotes nuclear translocation and downstream signaling cascades, and mediates multiple biological effects including cell proliferation, inflammatory activation, metabolic reprogramming and malignant transformation. The phosphorylation level of Thr202/Tyr204 directly reflects the activation status of the MAPK/ERK pathway, and its aberrant elevation is a typical pathological feature of tumors, chronic inflammation, fibrosis and proliferative diseases.
