Enriched motifs at sites bound uniquely by one EBNA protein. (A) Venn diagram summarizing the overlap of EBNA2 binding sites with sites bound by any EBNA3. Enriched motifs at sites bound only by EBNA2 (left box) or bound by any EBNA3, but not by EBNA2 (right box) are indicated, with corresponding P values and the names of any matching transcription factors. (B) Motifs enriched at sites bound uniquely by EBNA3A, EBNA3B, and EBNA3C (but not by EBNA2 or another EBNA3) are indicated, along with corresponding P values and matching transcription factors.
