In this study, I investigated the mechanism of mRNA expression of brain-derived neurotrophic factor (BDNF), which is involved in expressing a variety of neuronal functions. I found that RNA splicing of BDNF exon I-IX, which is one of alternative BDNF transcripts, was enhanced by Ca2+-CaMK signal evoked by neuronal activity. Moreover, a novel prepro-BDNF protein was generated from BDNF exon I-IX mRNA. These results provide a novel insight into BDNF expression in neurons
