Distribution of Mammalian miRNAs Found in Introns and Exons of Host Transcripts
The numbers given represent total numbers of miRNAs overlapping with transcripts in the human or mouse genome (see Methods). For comparison purposes, miRNAs in introns of transcripts are separated according to the nature of the host gene (protein coding vs. ncRNA). Nine of the `mixed' miRNAs are transcribed in introns or exons of alternatively spliced mlncRNA hosts the rest are associated with protein-coding host genes as well as mlncRNAs of alternatively spliced transcripts. Asterisk (*) denotes the number of mixed miRNAs derived from mlncRNA transcripts only.
