Transposable element composition of human lincRNAs. We intersected TE annotations with a catalog of 9,241 human lincRNAs. (a) TEs compose less lincRNA sequence than genomic background but much more than protein coding genes. Promoters for the two gene classes are more similar than the transcripts. (b) The lincRNA frequencies of many specific TE families differ significantly (based on a shuffling statistical test) from their genomic averages. Larger families are to the right. Enrichments are above zero on the y-axis, and depletions are below zero. ERV1 families (labeled in blue) are particularly enriched.
