  1. aThe locations of TTS characterized using PET data from eight ENCODE cell types were characterized relative to known human gene models Percentages shown are the percent of TTS in a location derived from a TE family.
  2. bTTS genic locations are shown for non TE-TTS and for the top eight TTS contributing TE families.
  3. cTTS located within 250 bp of canonical TTS.
  4. dTTS located up to 5 kb downstream of previously canonical TTS.
