Monoclonal antibodies reactive with either gag or fps portions of the wild-type Fujinami sarcoma virus transforming protein have been used to probe the structure of proteins encoded by mutant genomes constructed in vitro. The pattern of immunoreactivity suggests that the functional domain defined in genetic studies (Stone et al., Cell 37:549-558, 1984) corresponds to a discrete immunological domain in the native, wild-type Fujinami sarcoma virus protein. At least one mutation affecting both the structure and function of the proposed NH2-terminal fps-specific domain encodes a product with high specific activities in kinase assays. Furthermore, a cell line expressing high levels of this mutant protein is only moderately transformed. The striking correspondence between the immunological domain defined here and the functional domain inferred from the results of transfection experiments suggests that this non-kinase-specifying region constitutes a discrete structural as well as functional component of the viral protein.
