UniProtKB description:  Multifunctional protein that plays a role in the replication and long-term persistence of the viral episomal genome in dividing cells. Binds to mitotic chromosomes via its N-terminal region and to a 16-bp imperfect palindrome within the origin of replication (oriP) located in the viral terminal repeat (TR) through its C-terminal. Tethers viral episomes to chromosomes during mitosis. Plays a critical role in the shutdown of lytic gene expression during the early stage of infection by interacting with host TRIM28. Plays also a role in the repression of host NF-kappa-B activity upon TNF-alpha stimulation by promoting the proteasomal degradation of host RELA (PubMed:21697472). Promotes nuclear localization and cleavage of host STAT6 leading to constitutive activation of the IL13/STAT6 signaling pathway to promote viral latency (PubMed:28099521). Interacts with and modulates the histone methyltransferase MLL1 complex activity, leading to its recruitment on viral DNA terminal repeats changing the dynamic of histone H3 methylated 'Lys-4'(H3K4me) profile during the initial hours following infection (PubMed:34850113).
