The expression of the synaptic vesicle membrane protein, synaptophysin, was analyzed during postnatal development of the mouse cerebrum using a quantitative immunoblotting procedure. From birth to adulthood, the relative contents of synaptophysin increased 80-fold, reaching a final level of 3.5 micrograms/mg of total protein. The time course of accumulation suggests that synaptophysin expression is correlated with synaptogenesis. Thus synaptophysin may be used as a reliable marker of nerve terminal differentiation.
