Figure 2.

PC structure and three transcript variants. The coding exons of PC are represented by rectangles with different patterns and Arabic numbers on the top. The four untranslated exons (UEs) are labeled UE1-UE4 (top left). The arrows before UE1, UE2, and UE4 represent the transcription initiation sites. Three transcript variants are shown with the same coding region and different noncoding exons in the 5'-UTR and the reference sequences for the three splice variants are given.
