ID:GOLP3_HUMAN DESCRIPTION: RecName: Full=Golgi phosphoprotein 3; AltName: Full=Coat protein GPP34; AltName: Full=Mitochondrial DNA absence factor; Short=MIDAS; FUNCTION: Mediates the cis and medial Golgi localization of mannosyltransferases through direct binding of their cytosolic domains. Involved in modulation of mTOR signaling. Involved in the regulation of mitochondrial lipids, leading to increase of mitochondrial mass. Potential oncogene. SUBUNIT: Homodimer. Interacts with VPS35. INTERACTION: Q92614:MYO18A; NbExp=4; IntAct=EBI-2465479, EBI-949059; P12520:vpr (xeno); NbExp=3; IntAct=EBI-2465479, EBI-6164519; SUBCELLULAR LOCATION: Cell membrane (By similarity). Endosome (By similarity). Cytoplasm. Golgi apparatus, Golgi stack membrane; Peripheral membrane protein; Cytoplasmic side. Mitochondrion intermembrane space. Note=Phosphatidylinositol 4-phosphate (PtdIns4P) binding is essential for Golgi localization. TISSUE SPECIFICITY: Detected in muscle fibers of patients with mitochondrial diseases; not detected in normal muscle fibers. INDUCTION: Activated by depletion of mitochondrial DNA. PTM: Phosphorylated (By similarity). MISCELLANEOUS: Modulates sensitivity to rapamycin. Tumors expressing this protein are more sensitive to rapamycin in vivo. SIMILARITY: Belongs to the GOLPH3/VPS74 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.
