  1. EBVaGCs, EBV-associated gastric carcinomas; NPCs, nasopharyngeal carcinomas; TWs, throat washings from healthy donors.
  2. TAD: transactivation domain
  3. NLS: nuclear localization signals
  4. del: deletion
  5. RG domain: arginine-glycine repeat motif domain
  6. Amino acid: R is arginine, M is methionine, P is proline, T is theronine, Q is glutamine, K is lysine, G is glycine, I is isoleucine, L is leucine, E is glutamic, H is histidine
