Erk2 Protein is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
The ERK2 protein (Extracellular Signal-Regulated Kinase 2), encoded by MAPK1, is a serine/threonine kinase central to the MAPK/ERK signaling pathway. It is involved in neuronal development, synaptic plasticity, learning, and memory. Dysregulated ERK signaling contributes to neurodegeneration.
