Tissue-specific usage of PAPs. (A) The number of PAPs that are used in a tissue-specific manner. For the detailed definition of the tissue specificity, see the Methods section. (B) Examples of tissue-specific PAPs. The x-axes represent the genomic positions and the bars represent the number of 5′-ends of the oligo-cap cDNAs mapped at the corresponding genomic positions (TSSs). White bars show the tissue-specific usage of the corresponding PAPs observed in the indicated tissues.
