Distribution of p53 sites in ERV/LTR elements
| ERV category | Fragment no. | Copies with p53 sites | Percentage | Sites/fragment | Sites/kb |
|---|---|---|---|---|---|
| All ERVs | 319,106 | 1,509 | 0.47 | 0.0048 | 0.011 |
| LTR10B1 | 246 | 77 | 31.30 | 0.43 | 1.4 |
| LTR10C | 512 | 47 | 9.18 | 0.11 | 0.25 |
| LTR10D | 190 | 35 | 18.42 | 0.19 | 0.45 |
| LTR10E | 252 | 69 | 27.38 | 0.44 | 0.96 |
| MER61C | 294 | 157 | 53.40 | 0.53 | 1.5 |
| MER61E | 316 | 112 | 35.44 | 0.36 | 0.95 |
ERV LTRs are separated into those that contain p53 sites and those that do not, and overlap with PET3 + loci is determined for each set. Enrichment is determined as a ratio of the two overlap fractions. P value is calculated based on hypergeometric distribution. N/A, not available.
