ID:FNTA_MOUSE DESCRIPTION: RecName: Full=Protein farnesyltransferase/geranylgeranyltransferase type-1 subunit alpha; EC=2.5.1.58; EC=2.5.1.59; AltName: Full=CAAX farnesyltransferase subunit alpha; AltName: Full=FTase-alpha; AltName: Full=Ras proteins prenyltransferase subunit alpha; AltName: Full=Type I protein geranyl-geranyltransferase subunit alpha; Short=GGTase-I-alpha; FUNCTION: Catalyzes 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. The alpha subunit is thought to participate in a stable complex with the substrate. The beta subunit binds the peptide substrate. Through RAC1 prenylation and activation may positively regulate neuromuscular junction development downstream of MUSK. CATALYTIC ACTIVITY: Farnesyl diphosphate + protein-cysteine = S- farnesyl protein + diphosphate. CATALYTIC ACTIVITY: Geranylgeranyl diphosphate + protein-cysteine = S-geranylgeranyl-protein + diphosphate. ENZYME REGULATION: Activated by the AGRIN-induced phosphorylation which is mediated by MUSK. SUBUNIT: Heterodimer of an alpha and a beta subunit. Interacts with MUSK; the interaction is direct and mediates AGRIN-induced phosphorylation of FNTA. PTM: Phosphorylated. Phosphorylation is mediated by MUSK upon AGRIN stimulation and results in the activation of FNTA. SIMILARITY: Belongs to the protein prenyltransferase subunit alpha family. SIMILARITY: Contains 5 PFTA repeats.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

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.
