GAP43 (Growth Associated Protein 43, also known as neuromodulin) is a neuronal phosphoprotein specifically expressed in growing neurons during development and regeneration. GAP43 is a critical determinant of axonal outgrowth and synaptic plasticity. It localizes to the growth cone membrane and regulates actin cytoskeleton dynamics, neurotransmitter release, and second messenger signaling. GAP43 expression is re-induced following neuronal injury and in neurodegenerative diseases, reflecting attempted neural regeneration.
