The protein encoded by this gene is a member of choline/ethanolamine kinase family which catalyzes the first step of phosphatidylethanolamine (PtdEtn) biosynthesis via the cytidine diphosphate (CDP) ethanolamine pathway. Alternative splicing results in multiple transcript variants. ETNK2 (Ethanolamine Kinase 2) is a Protein Coding gene. Among its related pathways are phosphatidylethanolamine biosynthesis II and Glycerophospholipid biosynthesis. GO annotations related to this gene include transferase activity, transferring phosphorus-containing groups and ethanolamine kinase activity. An important paralog of this gene is ETNK1.
