Summaries for CEPT1 Gene

Entrez Gene Summary for CEPT1 Gene

  • Cholinephosphotransferase catalyses the final step in the synthesis of phosphatidylcholine by the transfer of phosphocholine from CDP-choline to diacylglycerol. The synthesis of phosphatidylethanolamine by ethanolaminephosphotransferase occurs using an analogous reaction. This gene codes for a choline/ethanolaminephosphotransferase. The protein can synthesize either choline- or ethanolamine- containing phospholipids. Two alternatively spliced transcripts encoding the same isoform have been identified.

GeneCards Summary for CEPT1 Gene

CEPT1 (Choline/Ethanolamine Phosphotransferase 1) is a Protein Coding gene. Among its related pathways are Metabolism and Metabolism. GO annotations related to this gene include diacylglycerol cholinephosphotransferase activity and ethanolaminephosphotransferase activity. An important paralog of this gene is EPT1.

UniProtKB/Swiss-Prot for CEPT1 Gene

  • Catalyzes both phosphatidylcholine and phosphatidylethanolamine biosynthesis from CDP-choline and CDP-ethanolamine, respectively. Involved in protein-dependent process of phospholipid transport to distribute phosphatidyl choline to the lumenal surface. Has a higher cholinephosphotransferase activity than ethanolaminephosphotransferase activity.
