Figure 1

Human BDNF gene structure. In the figure the structure of the human BDNF gene is shown; the gene contains 11 exons (I–IX, plus Vh and VIIIh), which combine to many different transcripts. Coding DNA sequence (CDS) is in exon IX. Alternative splice-donor sites and CpG islands are also reported. BDNF, brain-derived neurotrophic factor.
