Human Gene DOLK (ENST00000372586.4) from GENCODE V44
Description: Homo sapiens dolichol kinase (DOLK), mRNA. (from RefSeq NM_014908) RefSeq Summary (NM_014908): The protein encoded by this gene catalyzes the CTP-mediated phosphorylation of dolichol, and is involved in the synthesis of Dol-P-Man, which is an essential glycosyl carrier lipid for C- and O-mannosylation, N- and O-linked glycosylation of proteins, and for the biosynthesis of glycosyl phosphatidylinositol anchors in endoplasmic reticulum. Mutations in this gene are associated with dolichol kinase deficiency.[provided by RefSeq, Apr 2010]. Gencode Transcript: ENST00000372586.4 Gencode Gene: ENSG00000175283.8 Transcript (Including UTRs) Position: hg38 chr9:128,945,530-128,947,603 Size: 2,074 Total Exon Count: 1 Strand: - Coding Region Position: hg38 chr9:128,945,687-128,947,303 Size: 1,617 Coding Exon Count: 1
ID:DOLK_HUMAN DESCRIPTION: RecName: Full=Dolichol kinase; EC=2.7.1.108; AltName: Full=Transmembrane protein 15; FUNCTION: Involved in the synthesis of the sugar donor Dol-P-Man which is required in the synthesis of N-linked and O-linked oligosaccharides and for that of GPI anchors (By similarity). CATALYTIC ACTIVITY: CTP + dolichol = CDP + dolichyl phosphate. SUBCELLULAR LOCATION: Endoplasmic reticulum membrane; Multi-pass membrane protein (Potential). TISSUE SPECIFICITY: Ubiquitous. DISEASE: Defects in DOLK are the cause of congenital disorder of glycosylation type 1M (CDG1M) [MIM:610768]; also known as dolichol kinase deficiency. CDGs are a family of severe inherited diseases caused by a defect in glycoprotein biosynthesis. They are characterized by under-glycosylated serum glycoproteins. These multisystem disorders present with a wide variety of clinical features, such as disorders of the nervous system development, psychomotor retardation, dysmorphic features, hypotonia, coagulation disorders, and immunodeficiency. The broad spectrum of features reflects the critical role of N-glycoproteins during embryonic development, differentiation, and maintenance of cell functions. CDG1M is a very severe disorder with death occurring in early infancy. MISCELLANEOUS: Complements the defects in growth, dolichol kinase activity and protein N-glycosylation at the restrictive temperature in yeast sec59 mutant cells. SIMILARITY: Belongs to the polyprenol kinase family. SEQUENCE CAUTION: Sequence=BAA83046.2; Type=Erroneous initiation;
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.
