Proteins synthesized in African swine fever virus-infected cells analyzed by two-dimensional gel electrophoresis.

At least 74 acidic and 37 basic proteins are synthesized in African swine fever virus (ASFV)-infected monkey cells not detected in uninfected cells analyzed by two-dimensional gel electrophoresis. Essentially all the proteins synthesized early during infection are also observed at late times. The use of inhibitors such as cycloheximide and phosphonoacetate has led to the identification of 34 immediate early and 13 delayed early polypeptides. Therefore 64 proteins were classified as late polypeptides. Several ASFV-induced proteins are phosphorylated as proteins a1, a4, a20, a41, a48, a49, a51, a52, a55, a58, a67, b2, b12, b28, and b32.
