Figure 5.
Comparison of read abundance from canonical miRNA loci and mirtrons. Plotted are the total miRNA/star reads, including 3′-trimmed reads, collected from the 501 human and 236 mouse small RNA data sets; each bar represents an individual locus. Read numbers were normalized for number of genomic matches. The highest expressed canonical miRNAs and mirtrons are indicated. Our annotation of confident mirtrons required at least 50 miRNA/star reads; note that hundreds of loci deposited in miRBase do not meet this minimum. The underlying data used to generate this table are presented in Supplemental Table S7.
