GAP43 (B-50, F1, neuromodulin) is a phosphoprotein found in the presynaptic membranes of neurons, where it may have important roles in the maintenance of long-term potentiation and synaptic plasticity. Regulation of GAP43 activity may occur through PKC phosphorylation of Ser-41, which occurs during neurotransmitter release in mature neurons. Calmodulin may be a negative regulator of GAP43, since it binds to GAP43 when Ca2+ is low and neuronal activity is minimal. GAP43 is a major component of the growth cone in axons of developing neurons. Thus, it may have roles in axon development and synaptogenesis.

Western blot of mouse brain lysate. The blot was probed with mouse monoclonal anti-GAP43 (N-terminal region) antibody at 1:500 (lane 1) or 1:1000 (lane 2).

Formalin fixed, citric acid treated parafin sections of E7 chick spinal cord. Sections were probed with anti-GAP43 (GM3331) then anti-mouse:HRP before detection using DAB. (Image provided by Carl Hobbs and Dr. Pat Doherty at Wolfson Centre for Age-Related Diseases, King's College London).

Clone (M333) was generated from a sequence corresponding to amino acids in the N-terminal region of the human GAP43. This sequence has high homology to rat and mouse GAP43.
