Abstract:

Monkey cells synthesizing SV40 large T antigen were lysed and the extracts immunoprecipitated with either monoclonal anti-T antibody or monoclonal antibody to p110-114, the product of the retinoblastoma susceptibility gene (Rb). T and p110-114 coprecipitated in each case, implying that the proteins are complexed with each other. Substitution and internal deletion mutants of T that contain structural alterations in a ten residue, transformation-controlling domain failed to complex with p110-114. In contrast, T mutants bearing structural changes outside of this domain bound to p110-114. These results are consistent with a model for transformation by SV40 which, at least in part, involves T/p110-114 complex formation and the perturbation of Rb protein and/or T function.
