About This Section

Entrez Gene summary for CHKB:

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)

UniProtKB/Swiss-Prot: CHKB_HUMAN, Q9Y259

Function: 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
