FIGURE 8.

Classes of bicistronic and monocistronic transcripts derived from adjacent loci. Diagrams for two adjacent loci are depicted with their intergenic region (IGR). White boxes indicate that each ORF is as annotated in current gene models for the individual loci with all introns spliced as predicted. Gray boxes indicate that the ORF is altered from predictions due to splicing of introns at alternate positions within the coding region of the transcript, to N-terminal extension of coding sequences due to transcript initiation at sites upstream from the predicted translation start site, or to N-terminal truncation of coding sequences due to placement of the 5′ end of the transcript downstream from the predicted translation start site. Vertical lines designate the translation start and stop codons used in each ORF. The numbers of cDNAs in each category are as follows: A (7), B (2), C–J (1 each), K (2), L–N (1 each), O (7), P (12), Q (6), R (1), S (5), T (1), U (1), V (3), W (2).
