abstract:Choline Kinase (also known as CK,ChoK and Choline Phosphokinase) is an enzyme which catalyzes the first reaction in the choline pathway for phosphatidylcholine (PC) biosynthesis.This reaction involves the transfer of a phosphate group from ATP to choline in order to form phosphocholine.
A responsiveelement, DRE2 was foundinthe promoterregionof the gene, which indicated thatthe cholinekinasegene expression might be inducible by the dehydration.
