Mapping of HPV-11 E1 binding site and determination of other important cis elements for replication of the origin.

چکیده
The viral proteins E1 and E2 are essential for the replication of the HPV-11 origin. We have now mapped the E1 binding site (E1BS) and show by mutation analysis that the E1BS and an adjoining poly(A)-rich region are necessary for efficient replication of the origin. We have also shown, using suboptimal levels of E1 protein, that enhancement of E1 binding by E2 partially protects the E1BS. Finally, we show that E1 can enhance the binding of E2 even in the absence of the E1BS.

The Varicella-Zoster Virus (VZV) genome contains both cis-acting and trans-acting elements, which are important in viral DNA replication. The cis-acting elements consist of two copies of oriS, and the trans-acting elements are those genes whose products are required for virus DNA replication. It has been shown that each of the seven genes required for ori-dependent DNA synthesis of Herpes Simpl...
متن کاملFunctional mapping of the human papillomavirus type 16 E1 cistron.
Replication of the double-stranded, circular human papillomavirus (HPV) genomes requires the viral DNA replicase E1. Here, we report an initial characterization of the E1 cistron of HPV type 16 (HPV-16), the most common oncogenic mucosal HPV type found in cervical and some head and neck cancers. The first step in HPV DNA replication is an initial burst of plasmid viral DNA amplification. Comple...

The long control region (LCR) of human papillomavirus type 16 (HPV-16) has a size of 850 bp (about 12% of the viral genome) and regulates transcription and replication of the viral DNA. The 5' segment of the LCR contains transcription termination signals and a nuclear matrix attachment region, the central segment contains an epithelial cell-specific enhancer, and the 3' segment contains the rep...
متن کاملAssociation of the human papillomavirus type 11 E1 protein with histone H1.
The E1 and E2 proteins are the only virus-encoded factors required for human papillomavirus (HPV) DNA replication. The E1 protein is a DNA helicase responsible for initiation of DNA replication at the viral origin. Its recruitment to the origin is facilitated by binding to E2, for which specific recognition elements are located at the origin. The remaining replication functions for the virus, p...
متن کاملTranscription factor YY1 represses cell-free replication from human papillomavirus origins.
We have established cell-free replication for the human papillomavirus type 18 (HPV-18) origin of replication (ori)-containing DNA by using purified HPV-18 E1 and E2 gene products expressed as fusion proteins in Escherichia coli. The transcription factor YY1 has been shown to regulate RNA transcription by binding to a sequence overlapping the putative E1 protein binding site in the HPV-18 ori. ...
