MAP2K2 (Mitogen-Activated Protein Kinase Kinase 2) encodes MEK2, a dual-specificity serine/threonine kinase that functions downstream of RAF kinases in the RAS-RAF-MEK-ERK (MAPK) signaling cascade. MEK2 phosphorylates and activates ERK1/2, completing the kinase cascade that regulates cellular proliferation, differentiation, survival, and apoptosis. MEK2 has overlapping but distinct functions from its paralog MEK1 (MAP2K1), and both are essential for proper neuronal development and function. In the brain, MEK2-ERK signaling contributes to synaptic plasticity, dendritic spine morphology, learning, memory, and neuronal survival. Dysregulated MEK-ERK signaling is implicated in Alzheimer's disease, Parkinson's disease, and various neurodevelopmental disorders.
