Human Gene FDPS (ENST00000467076.5) Description and Page Index
  Description: Homo sapiens farnesyl diphosphate synthase (FDPS), transcript variant 4, mRNA. (from RefSeq NM_001242824)
RefSeq Summary (NM_001135822): This gene encodes an enzyme that catalyzes the production of geranyl pyrophosphate and farnesyl pyrophosphate from isopentenyl pyrophosphate and dimethylallyl pyrophosphate. The resulting product, farnesyl pyrophosphate, is a key intermediate in cholesterol and sterol biosynthesis, a substrate for protein farnesylation and geranylgeranylation, and a ligand or agonist for certain hormone receptors and growth receptors. Drugs that inhibit this enzyme prevent the post-translational modifications of small GTPases and have been used to treat diseases related to bone resorption. Multiple pseudogenes have been found on chromosomes 1, 7, 14, 15, 21 and X. Multiple transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Oct 2008].

DESCRIPTION: RecName: Full=Farnesyl pyrophosphate synthase; Short=FPP synthase; Short=FPS; EC=; AltName: Full=(2E,6E)-farnesyl diphosphate synthase; AltName: Full=Dimethylallyltranstransferase; EC=; AltName: Full=Farnesyl diphosphate synthase; AltName: Full=Geranyltranstransferase;
FUNCTION: Key enzyme in isoprenoid biosynthesis which catalyzes the formation of farnesyl diphosphate (FPP), a precursor for several classes of essential metabolites including sterols, dolichols, carotenoids, and ubiquinones. FPP also serves as substrate for protein farnesylation and geranylgeranylation. Catalyzes the sequential condensation of isopentenyl pyrophosphate with the allylic pyrophosphates, dimethylallyl pyrophosphate, and then with the resultant geranylpyrophosphate to the ultimate product farnesyl pyrophosphate.
CATALYTIC ACTIVITY: Dimethylallyl diphosphate + isopentenyl diphosphate = diphosphate + geranyl diphosphate.
CATALYTIC ACTIVITY: Geranyl diphosphate + isopentenyl diphosphate = diphosphate + (2E,6E)-farnesyl diphosphate.
COFACTOR: Binds 3 magnesium ions per subunit.
ENZYME REGULATION: Inactivated by interferon-induced RSAD2. This inactivation may result of disruption of lipid rafts at the plasma membrane, and thus have an antiviral effect since many enveloped viruses need lipid rafts to bud efficiently out of the cell.
PATHWAY: Isoprenoid biosynthesis; farnesyl diphosphate biosynthesis; farnesyl diphosphate from geranyl diphosphate and isopentenyl diphosphate: step 1/1.
PATHWAY: Isoprenoid biosynthesis; geranyl diphosphate biosynthesis; geranyl diphosphate from dimethylallyl diphosphate and isopentenyl diphosphate: step 1/1.
SUBUNIT: Homodimer. Interacts with RSAD2. Interacts with HTLV-1 protein p13(II).
SIMILARITY: Belongs to the FPP/GGPP synthase family.
CAUTION: It is uncertain whether Met-1 or Met-67 is the initiator.
SEQUENCE CAUTION: Sequence=AAA52423.1; Type=Erroneous initiation; Sequence=BAA03523.2; Type=Erroneous initiation;

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
