Epstein–Barr virus nuclear antigen 3

The Epstein–Barr virus nuclear antigen 3 is a family of viral proteins associated with the Epstein–Barr virus. A typical EBV genome contains three such proteins:

EBNA-3A
EBNA-3B
EBNA-3C

These genes also bind the host RBP-Jκ protein.
EBNA-3C can recruit a ubiquitin ligase and has been shown to target cell-cycle regulators such as retinoblastoma protein.
