Abstract
B-50 (GAP-43) is a neural, membrane-associated protein that has been implicated in neurite outgrowth and guidance. Following stable transfection of Rat1 fibroblasts with B-50 cDNA we observed a dispersed distribution of B-50 immunoreactivity in flattened resting cells. In contrast, motile cells exhibited high concentrations of B-50 at the leading edge
