Eight distinct antigenic determinants, or epitopes (labeled a-h) were identified on endogenous ecotropic murine leukemia virus (MuLV) gp70s using a series of murine and rat monoclonal antibodies. These epitopes were characterized by their distribution patterns in a panel of cloned MuLVs, and by their localization in fragments of gp70 generated either by spontaneous breakdown of purified gp70, or by controlled proteolysis of gp70 in solubilized virions. A major 32K carboxy terminal fragment was formed which contained epitopes b, c, and f. This fragment also possessed the p15(E) disulfide linkage site, and contained approximately four complex (type 1) carbohydrate chains. An amino terminal 35K fragment contained epitopes a, d, g, and h, and possessed two glycosylated sites, including a site which occasionally retained an endoglycosidase H-sensitive oligosaccharide chain. A related 49K fragment was also obtained which included the entire 35K region and contained an additional sequence bearing epitope e. In a series of dual-tropic MCF-type viruses studied, only those epitopes located in the 32K fragment were ever retained, indicating that for these recombinant viruses at least a portion of that domain was derived from the ecotropic parent. A model is presented indicating the likely orientation of these fragments and their structural characteristics.
