Presence of direct repeats, viral transcription start sites, and poly-A sequences in some virus-related genomic integrations.

Sequences most resembling the canonical transcription start site (TSS) and canonical poly-A sequences are underlined. Direct repeat sequences flanking virus-derived integrations are shown in bold.
1)Location of the TSS relative to the estimated position of the coding sequence start, based on the present day viral protein. The expected location is −11 for Bornavirus EBLN insertions, −414 for EBOV EELN insertions, −55 for MARV EELN insertions; and −92 to −97 for EEL35 insertions.
2)Location of the poly-A sequence relative to the estimated position of the coding sequence start, based on the present day viral protein. The expected location is 1110 for Bornavirus EBLN insertions, 2545 for EBOV EELN insertions, 2730 for MARV EELN insertions, and 1268 to 1455 for EEL35 insertions.
3)Bornavirus integration hsEBLN-2 in human genome is directly followed by a repeat element AluSx, also observed by Hoire et al [5]. These two integrated sequences are surrounded by a common direct repeat.
