Human Gene UBIAD1 (ENST00000376804.2) from GENCODE V38
Description: Homo sapiens UbiA prenyltransferase domain containing 1 (UBIAD1), transcript variant 3, mRNA. (from RefSeq NM_001330350) RefSeq Summary (NM_001330350): This gene encodes a protein thought to be involved in cholesterol and phospholipid metabolism. Mutations in this gene are associated with Schnyder crystalline corneal dystrophy. [provided by RefSeq, Oct 2008]. Gencode Transcript: ENST00000376804.2 Gencode Gene: ENSG00000120942.14 Transcript (Including UTRs) Position: hg38 chr1:11,273,528-11,295,164 Size: 21,637 Total Exon Count: 2 Strand: + Coding Region Position: hg38 chr1:11,273,532-11,294,883 Size: 21,352 Coding Exon Count: 2
ID:UBIA1_HUMAN DESCRIPTION: RecName: Full=UbiA prenyltransferase domain-containing protein 1; EC=2.5.1.-; AltName: Full=Transitional epithelial response protein 1; FUNCTION: Prenyltransferase that mediates the formation of menaquinone-4 (MK-4), a vitamin K2 isoform present at high concentrations in the brain, kidney and pancreas. Mediates the conversion of phylloquinone (PK) into menaquinone-4 (MK-4), probably by cleaving the side chain of phylloquinone (PK) to release 2-methyl-1,4-naphthoquinone (menadione; K3) and then prenylating it with geranylgeranyl pyrophosphate (GGPP) to form MK-4. PATHWAY: Cofactor biosynthesis; menaquinone biosynthesis. SUBCELLULAR LOCATION: Endoplasmic reticulum membrane; Multi-pass membrane protein. Cytoplasm. Nucleus. Mitochondrion. TISSUE SPECIFICITY: Ubiquitously expressed. DISEASE: Defects in UBIAD1 are the cause of crystalline corneal dystrophy of Schnyder (SCCD) [MIM:121800]. SCCD is a rare autosomal dominant disease characterized by progressive corneal opacification resulting from abnormal deposition of cholesterol and phospholipids. MISCELLANEOUS: Strongly down-regulated in transitional cell carcinoma of the bladder and in prostate carcinoma (at protein level). SIMILARITY: Belongs to the UbiA prenyltransferase 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.

ModBase Predicted Comparative 3D Structure on Q9Y5Z9
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.
