Interactions between polyomavirus medium T antigen and three cellular proteins of 88, 61, and 37 kilodaltons.


Affinity-purified medium T antigen of wild-type polyomavirus and dl8, a transforming mutant with a deletion in the medium T gene, is associated with three cellular proteins with apparent molecular weights of 88,000 (88K protein), 61,000 (61K protein), and 37,000 (37K protein). Medium T antigen encoded by the nontransforming hrt mutants fails to associate… (More)
