Acylated simian virus 40-specific proteins in the plasma membrane of HeLa cells infected with adenovirus 2-simian virus 40 hybrid virus Ad2+ND2.

HeLa cells infected with the adenovirus 2-simian virus 40 (Ad2+SV40) hybrid virus Ad2+ND2 were labeled with either [35S]methionine or [3H]palmitate and fractionated into cytoplasmic, nuclear, and plasma membrane fractions. Analysis of these fractions by sodium dodecyl sulfate-polyacrylamide gel electrophoresis showed that the SV40-specific proteins in the plasma membrane fraction were specificially acylated.
