Mouse lincRNAs share TE composition properties. (a) Similar to the human genome, in a catalog of 981 mouse lincRNAs, TEs are depleted overall relative to the genomic background frequency, but still a substantial 33% of sequence is TE-derived. (b) TEs also exhibit biased composition in mouse lincRNAs, with strong L1 depletion and ERV1 enrichment, matching observations in human.
