The function of Ensembl gene identifier ENSG00000175283 (DOLK, dolichol kinase) is as follows. Catalyzes CTP-mediated phosphorylation of dolichol, the terminal step in de novo dolichyl monophosphate (Dol-P) biosynthesis (PubMed:12213788, PubMed:16923818, PubMed:17273964, PubMed:22242004). Dol-P is a lipid carrier essential for the synthesis of N-linked and O- linked oligosaccharides and for GPI anchors (PubMed:12213788). {ECO:0000269|PubMed:12213788, ECO:0000269|PubMed:16923818, ECO:0000269|PubMed:17273964, ECO:0000269|PubMed:22242004}.
