Growth associated proteins

(Science: growth factor) group of developmentally regulated polypeptides thought to be critical for the formation of neural circuitry. The acidic membrane phosphoprotein gap 43 is synthesised and transported down regenerating and developing axons, pp46 localised in growth cone membranes during embryogenesis, B 50 in mature presynaptic membranes in the regulation of phosphotidylinositol turnover and F1 in the hippocampus during long-term potentiation, are now all known to be the same protein.
