Improved Production of Prenylated Protein in Insect Cells
KRAS and other Ras-family enzymes are an important component of over 30% of human cancers, however, no effective therapeutics targeting Ras or Ras-driven cancers are currently available. The production of Ras proteins in vitro is required for the identification and characterization of Ras targeting drugs. An important step in producing the Ras protein involves prenylation of the C-terminus of the protein via farnesyltransferase, a modification that does not occur in prokaryotic organisms. Previous attempts to generate properly processed Ras in eukaryotic cells has
