  • Application notes
    Is unsuitable for ICC.
  • Target

    • Function

      Catalyzes the transfer of a farnesyl moiety from farnesyl pyrophosphate to a cysteine at the fourth position from the C-terminus of several proteins. The beta subunit is responsible for peptide-binding.
    • Sequence similarities

      Belongs to the protein prenyltransferase subunit beta family.
      Contains 5 PFTB repeats.
