Choline kinase (CK) and ethanolamine kinase (EK) catalyze the phosphorylation of choline/ethanolamine to phosphocholine/phosphoethanolamine. This is the first enzyme in the biosynthesis of phosphatidylcholine/phosphatidylethanolamine in all animal cells. The highly purified CKs from mammalian sources and their recombinant gene products have been shown to have EK activity also, indicating that both activities reside on the same protein. The choline kinase-like protein encoded by CHKL belongs to the choline/ethanolamine kinase family; however, its exact function is not known. Read-through transcripts are expressed from this locus that include exons from the downstream CPT1B locus. [provided by RefSeq, Jun 2009]
GeneCards Summary for CHKB Gene
CHKB (Choline Kinase Beta) is a Protein Coding gene. Diseases associated with CHKB include Muscular Dystrophy, Congenital, Megaconial Type and Proximal Myopathy With Focal Depletion Of Mitochondria. Among its related pathways are Mitochondrial LC-Fatty Acid Beta-Oxidation and Glycerophospholipid biosynthesis. Gene Ontology (GO) annotations related to this gene include transferase activity, transferring phosphorus-containing groups and choline kinase activity. An important paralog of this gene is CHKA.
