Interferon regulatory factor 7: a key cellular mediator of LMP-1 in EBV latency and transformation.
Interferon regulatory factor 7 (IRF-7) was cloned within the biological context of Epstein-Barr virus (EBV) latency, and has an intimate relation with EBV. EBV latent membrane protein 1 (LMP-1) regulates IRF-7 both by inducing the expression of IRF-7 and by activating IRF-7 protein through phosphorylation and nuclear translocation in a post-translational manner. The activated IRF-7 then functio...
متن کاملCloning and sequencing of rainbow trout (Oncorhynchus mykiss) interferon regulatory factor 7
Interferon regulatory factor 7 (IRF7) gene was cloned from a subtractive cDNA library constructed with mRNAs obtained from rainbow trout (Oncorhynchus mykiss) macrophage cell line (RTS-11). Using expressed sequence tag clones of submitted IRF7 amino acid sequences, specific primers were designed. Results showed that IRF7 cDNA contains an ORF of 1251 nucleotides that translates into a 416 resi...
متن کاملThe latent membrane protein 1 of Epstein-Barr virus (EBV) primes EBV latency cells for type I interferon production.
Epstein-Barr virus (EBV) latency has been associated with a variety of human cancers. Latent membrane protein 1 (LMP-1) is one of the key viral proteins required for transformation of primary B cells in vitro and establishment of EBV latency. We have previously shown that LMP-1 induces the expression of several interferon (IFN)-stimulated genes and has antiviral effect (Zhang, J., Das, S. C., K...
متن کاملIRF-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...
متن کاملInterferon regulatory factor 4 is involved in Epstein-Barr virus-mediated transformation of human B lymphocytes.
Epstein-Barr virus (EBV) infection is associated with many human malignancies. In vitro, EBV transforms primary B lymphocytes into continuously growing lymphoblastoid cell lines. EBV latent membrane protein 1 (LMP-1) is required for EBV transformation processes. Interferon regulatory factor 4 (IRF-4) is a transcription factor and has oncogenic potential. We find that high levels of IRF-4 are as...
