  • CATEGORY enzyme
    SUBCELLULAR LOCALIZATION     plasma membrane
        intracellular
    intracellular,cytoplasm,cytosolic
    basic FUNCTION
  • catalyzing the transfer of a farnesyl or geranyl-geranyl moiety from farnesyl or geranyl-geranyl pyrophosphate to a cysteine at the fourth position from the C-terminus of several proteins having the C-terminal sequence Cys-aliphatic-aliphatic-X
  • promoting the prenylation of Ras
  • first step of a series of post translational modification of RAS
  • attachment of an isoprenoid lipid (a process termed prenylation) by FNTA or geranylgeranyltransferase type I (PGGT1B) is essential for the function of many signal transduction proteins involved in growth, differentiation, and oncogenesis
  • required for its association with the inner surface of the plasma membrane
  • also involved in maturation of other proteins including Ras familymembers, the gamma subunit of G proteins and nuclear lamins
  • acting as an acetylcholine receptor regulator
  • mediates posttranslational modification of proteins with isoprenoid lipids
  • functions of FNTA subunit that includes control of intracellular membrane trafficking
  • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism lipid/lipoprotein
    signaling signal transduction
  • neurotransmitter receptor metabolic process
  • protein amino acid farnesylation
  • protein amino acid geranylgeranylation
  • transforming growth factor beta receptor signaling pathway
  • a component
  • farnesyltransferase is an heterodimer of an alpha and a beta subunit (FNTA, FNTB)
  • participating in a stable complex with the substrate
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • via its tubulin-association, is a critical upstream regulator of HDAC6 activity and its expression could help stratify cancer patients that would most benefit from this treatment (Zhou 2009)
  • VPS4A was validated for direct binding to the FNTA subunit
  • cell & other
    REGULATION
    inhibited by by caspase-3 cleavage of the common alpha subunit during apoptosis (Kim 2001)
