ID:GEPH_HUMAN DESCRIPTION: RecName: Full=Gephyrin; Includes: RecName: Full=Molybdopterin adenylyltransferase; Short=MPT adenylyltransferase; EC=2.7.7.75; AltName: Full=Domain G; Includes: RecName: Full=Molybdopterin molybdenumtransferase; Short=MPT Mo-transferase; EC=2.10.1.1; AltName: Full=Domain E; FUNCTION: Microtubule-associated protein involved in membrane protein-cytoskeleton interactions. It is thought to anchor the inhibitory glycine receptor (GLYR) to subsynaptic microtubules (By similarity). Catalyzes two steps in the biosynthesis of the molybdenum cofactor. In the first step, molybdopterin is adenylated. Subsequently, molybdate is inserted into adenylated molybdopterin and AMP is released. CATALYTIC ACTIVITY: ATP + molybdopterin = diphosphate + adenylyl- molybdopterin. CATALYTIC ACTIVITY: Adenylyl-molybdopterin + molybdate = molybdenum cofactor + AMP. COFACTOR: Magnesium (By similarity). ENZYME REGULATION: Inhibited by copper and tungsten (By similarity). PATHWAY: Cofactor biosynthesis; molybdopterin biosynthesis. SUBUNIT: Homotrimer. Interacts with GABARAP (By similarity). Interacts with SRGAP2 (via SH3 domain) (By similarity). SUBCELLULAR LOCATION: Cell junction, synapse (By similarity). Cell junction, synapse, postsynaptic cell membrane; Peripheral membrane protein; Cytoplasmic side (By similarity). Cytoplasm, cytoskeleton (By similarity). Note=Cytoplasmic face of glycinergic postsynaptic membranes (By similarity). DISEASE: Defects in GPHN are the cause of molybdenum cofactor deficiency type C (MOCOD type C) [MIM:252150]. MOCOD type C is an autosomal recessive disease which leads to the pleiotropic loss of all molybdoenzyme activities and is characterized by severe neurological damage, neonatal seizures and early childhood death. SIMILARITY: In the N-terminal section; belongs to the MoaB/Mog family. SIMILARITY: In the C-terminal section; belongs to the MoeA family.

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.
