Neurotrophins are synthesized first as precursors called pro-neurotrophins, and their propeptides are then proteolytically removed to form mature neurotrophins. However, a significant proportion of total neurotrophins has been shown to be secreted as pro-neurotrophins. Furthermore, pro- and mature neurotrophins have been shown to elicit opposite effects on cell survival. Thus, the processing step of neurotrophins is very important. In order to understand the mechanism of neurotrophin processing, we focused on the two basic amino acid clusters in the pro-region of nerve growth factor (NGF). Various NGFs mutated at basic amino acids in the pro-region were introduced in COS7 and PC12 cells. The results indicated that these basic amino acid clusters were actually cleaved in the cells by furin, but that their cleavage contributed little to the production of mature NGF. However, one of the two sites was considered to contribute to mature NGF production depending on conditions used.
