Identification and mapping of polypeptides encoded by the P3HR-1 strain of Epstein-Barr virus.

Abstract
The Epstein-Barr virus (EBV)-specified polypeptides induced upon viral replication in the human lymphoblastoid P3HR-1 cell line were examined by immunoprecipitation with a high-titer human anti-EBV serum. Twenty-five predominant polypeptides were identified in cell extracts; 18 polypeptides were precipitated from cell-free translation reactions directed by total mRNA. Hybrid selection of mRNA to the BamHI DNA clones of the EBV genome and immunoprecipitation of the corresponding cell-free translation products revealed 98 EBV-specified polypeptides and their coding location along the viral genome. The viral polypeptides that bind reversibly to DNA-cellulose were characterized and the deduced map locations of this functional group of EBV-specified polypeptides is presented.
