Homologous cellular proteins associated with simian virus 40 small T antigen and polyomavirus medium T antigen

Abstract

The simian virus 40 small T-associated 56,000-Mr (56K) and 32K cellular proteins were shown to be closely related to the polyomavirus medium T-associated 61K and 37K cellular proteins as demonstrated by two-dimensional polyacrylamide gel electrophoresis and V8 protease peptide mapping.
