TSS usage and CpG dinucleotides at the 5' end of Snrpn. Expression levels of tag cluster T07R02CED41C, located at the 5' end of Snrpn on the reverse strand of chromosome 7, are shown. Only tissues with tpm (transcripts per million) above 100 and more than ten CAGE tags in the tag cluster are shown, and their expression levels are displayed as histograms. Gray backgrounds indicate regions with different tissue specificity from the remaining part of the tag cluster. Genome sequences are displayed below the graphs, and CpG sites are indicated by dots. CAGE, cap analysis of gene expression; TSS, transcription start site.
