The Epstein-Barr virus immediate-early protein BZLF1 induces both a G(2) and a mitotic block.

چکیده
The Epstein-Barr virus immediate-early protein BZLF1 is a transcriptional activator that mediates the switch from latent to lytic infection. Here we demonstrate that BZLF1 induces both a G(2) block and a mitotic block in HeLa cells and inhibits chromosome condensation. While the G(2) block is associated with decreased cyclin B1 in host cells and can be rescued by overexpression of cyclin B1, the mechanism for the mitotic defect is as yet undetermined.

Epstein-Barr virus BZLF1 protein binds to mitotic chromosomes.
Epstein-Barr virus (EBV) is a human herpesvirus that causes infectious mononucleosis and is associated with several types of cancers, including nasopharyngeal carcinoma and Burkitt's lymphoma. An EBV protein that plays an integral role during lytic replication is the immediate-early protein BZLF1. Our laboratory has found that BZLF1 (Z) localizes to host chromosomes during mitosis. Two Z-intera...
متن کاملTranscriptional repression by sumoylation of Epstein-Barr virus BZLF1 protein correlates with association of histone deacetylase.
The transition from latent to lytic phases of the Epstein-Barr virus life cycle is triggered by expression of a viral transactivator, BZLF1, that then induces expression of the viral immediate-early and early genes. The BZLF1 protein is post-translationally modified by a small ubiquitin-related modifier-1 (SUMO-1). Here we found that BZLF1 is conjugated at lysine 12 not only by SUMO-1 but also ...
متن کاملExpression of Epstein-Barr virus BZLF1 immediate-early protein induces p53 degradation independent of MDM2, leading to repression of p53-mediated transcription.
The Epstein-Barr virus (EBV) lytic program elicits ATM-dependent DNA damage response, resulting in phosphorylation of p53 at N-terminus, which prevents interaction with MDM2. Nevertheless, p53-downstream signaling is blocked. We found here that during the lytic infection p53 was actively degraded in a proteasome-dependent manner even with a reduced level of MDM2. BZLF1 protein enhanced the ubiq...
متن کاملBromodomain and extraterminal inhibitors block the Epstein-Barr virus lytic cycle at two distinct steps
Lytic infection by the Epstein-Barr virus (EBV) poses numerous health risks, such as infectious mononucleosis and lymphoproliferative disorder. Proteins in the bromodomain and extraterminal (BET) family regulate multiple stages of viral life cycles and provide promising intervention targets. Synthetic small molecules can bind to the bromodomains and disrupt function by preventing recognition of...
متن کاملActivation of Epstein-Barr virus replication in Hodgkin and Reed-Sternberg cells.
Recent evidence has shown that Hodgkin's disease (HD) is associated with Epstein-Barr virus (EBV) in a substantial number of cases and that in these cases EBV DNA is localized exclusively to Hodgkin and Reed-Sternberg (RS) cells. The virus genome is not silent in RS cells because two EBV latent gene products, latent membrane protein (LMP) and EB early region (EBER) transcripts, have recently be...
