Interferon regulatory factor 2 represses the Epstein-Barr virus BamHI Q latency promoter in type III latency.

Epstein-Barr virus (EBV) nuclear antigen 1 (EBNA-1) is the essential protein for maintenance of the EBV episome and establishment of latency. The BamHI Q promoter (Qp) is used for the transcription of EBNA-1 mRNA in type I and type II latency, which are EBV infection states exemplified by Burkitt's lymphoma and nasopharyngeal carcinoma. However, Qp is inactive in type III latency, and other pro...

IRF-7, a new interferon regulatory factor associated with Epstein-Barr virus latency.

The Epstein-Barr virus (EBV) BamHI Q promoter (Qp) is the only promoter used for the transcription of Epstein-Barr virus nuclear antigen 1 (EBNA-1) mRNA in cells in the most restricted (type I) latent infection state. However, Qp is inactive in type III latency. With the use of the yeast one-hybrid system, a new cellular gene has been identified that encodes proteins which bind to sequence in Q...

Epstein-Barr virus immortalization and latency.

Epstein-Barr virus infects human B lymphocytes. The interaction between the virus and these cells has been the subject of investigation for over three decades. Recent in vitro and in vivo studies, reviewed here, are revealing the mechanisms by which EBV induces and controls proliferation through the expression of six viral nuclear proteins and two plasma membrane proteins. This genetic program ...

Regulation of Epstein-Barr virus latency type by the chromatin boundary factor CTCF.

Epstein Barr virus (EBV) can establish distinct latency types with different growth-transforming properties. Type I latency and type III latency can be distinguished by the expression of EBNA2, which has been shown to be regulated, in part, by the EBNA1-dependent enhancer activity of the origin of replication (OriP). Here, we report that CTCF, a chromatin boundary factor with well-established e...

CpG methylation of the major Epstein-Barr virus latency promoter in Burkitt's lymphoma and Hodgkin's disease.

The Epstein-Barr virus (EBV) latency C promoter drives expression of a family of viral proteins commonly targeted by CD8 cytotoxic T cells. These proteins are not generally expressed in African Burkitt's lymphoma and in EBV-associated Hodgkin's disease. The failure to express these proteins is almost certainly an important factor in the evasion of immunosurveillance by EBV-associated tumors. In...
