Figure 3From: Both 5' and 3' flanks regulate Zebrafish brain-derived neurotrophic factor gene expressionSplicing of Zebrafish BDNF exons into mature transcripts The boxes are exons and the horizontal line represents 5' flanks, introns, and 3' flank. Angled lines to indicate splicing into mature transcripts connect the exons. The depicted combinations were identified by 5' RACE and cDNA cloning. Additional combinations may exist.Back to article page
