Protein TypeStructural Protein
Target ClassStructural Protein
FunctionGAP43 (also known as neuromodulin) is a neuronal phosphoprotein specifically expressed in growing neurons during development and regeneration.
Mechanism of ActionDrugs targeting GAP43 would enhance axonal growth cone formation and synaptic plasticity by promoting phosphorylation or membrane translocation of GAP43, thereby facilitating neurite outgrowth and synapse formation. Alternatively, agents could upregulate GAP43 expression to restore neuronal connectivity and compensate for age-related decline in neurodegenerative conditions.
