Protein Information (annotations from UniProt)

Database IDHIV0000601
UniProt IDQ9Y259
Primary gene name(s)CHKB
Synonym gene name(s)CHETK, CHKL
Protein nameCholine/ethanolamine kinase
Protein functionHas 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. {ECO:0000269|PubMed:19915674}.
