Summaries for ETNK1 Gene

Entrez Gene Summary for ETNK1 Gene

  • This gene encodes an ethanolamine kinase, which functions in the first committed step of the phosphatidylethanolamine synthesis pathway. This cytosolic enzyme is specific for ethanolamine and exhibits negligible kinase activity on choline. Alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Jul 2008]

GeneCards Summary for ETNK1 Gene

ETNK1 (Ethanolamine Kinase 1) is a Protein Coding gene. Among its related pathways are Metabolism and Glycerophospholipid biosynthesis. Gene Ontology (GO) annotations related to this gene include transferase activity, transferring phosphorus-containing groups and ethanolamine kinase activity. An important paralog of this gene is ETNK2.

UniProtKB/Swiss-Prot for ETNK1 Gene

  • Highly specific for ethanolamine phosphorylation. May be a rate-controlling step in phosphatidylethanolamine biosynthesis.
