Previous Symbols for CHKB Gene
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]

CHKB (Choline Kinase Beta) is a Protein Coding gene. Diseases associated with CHKB include spermatic cord torsion and japanese spotted fever. Among its related pathways are Metabolism and Metabolism. GO annotations related to this gene include ethanolamine kinase activity and choline kinase activity. An important paralog of this gene is ETNK1.
UniProtKB/Swiss-Prot for CHKB Gene
Has a key role in phospholipid biosynthesis. Catalyzes the first step in phosphatidylethanolamine biosynthesis. Phosphorylates ethanolamine, and can also act on choline (in vitro). Has higher activity with ethanolamine. May not significantly contribute to in vivo phosphatidylcholine biosynthesis.
