Summaries for ETNK2 Gene

Entrez Gene Summary for ETNK2 Gene

  • 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. [provided by RefSeq, Jul 2014]

GeneCards Summary for ETNK2 Gene
