Proteins of bovine leudemia virus: p. 15 is the major phosphorprotein.

Sodium dodecylsulfate-polyacrylamide gel electrophoresis of bovine leukemia virus (BLV) grown in fetal lamb kidney cells in the presence of 32P-phosphoric acid showed that the slightly basic 15000 D protein (pp 15) is the major phosphorylated component of the virus. This result further distinguishes BLV from mammalian type C viruses which possess acidic major phosphorproteins.
