ID:TPC_HUMAN DESCRIPTION: RecName: Full=Mitochondrial thiamine pyrophosphate carrier; AltName: Full=Mitochondrial uncoupling protein 1; AltName: Full=Solute carrier family 25 member 19; FUNCTION: Mitochondrial transporter mediating uptake of thiamine pyrophosphate (ThPP) into mitochondria. SUBCELLULAR LOCATION: Mitochondrion inner membrane; Multi-pass membrane protein. TISSUE SPECIFICITY: Expressed in all tissues examined except for placenta. Highest levels in colon, kidney, lung, testis, spleen, and brain. DISEASE: Defects in SLC25A19 are the cause of microcephaly Amish type (MCPHA) [MIM:607196]; also known as Amish lethal microcephaly. MCPHA is an autosomal recessive metabolic disorder characterized by severe congenital microcephaly, severe 2- ketoglutaric aciduria and death within the first year. DISEASE: Defects in SLC25A19 are the cause of striatal necrosis bilateral and progressive polyneuropathy (SNBPP) [MIM:613710]. A disease characterized by recurrent episodes of flaccid paralysis and encephalopathy associated with bilateral striatal necrosis and chronic progressive polyneuropathy. MISCELLANEOUS: The transmembrane helices are not perpendicular to the plane of the membrane, but cross the membrane at an angle. Odd-numbered transmembrane helices exhibit a sharp kink, due to the presence of a conserved proline residue (By similarity). SIMILARITY: Belongs to the mitochondrial carrier family. SIMILARITY: Contains 3 Solcar repeats. WEB RESOURCE: Name=GeneReviews; URL="http://www.ncbi.nlm.nih.gov/sites/GeneTests/lab/gene/SLC25A19";
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.
