- hEPT1
|
Gene Name
| EPT1 |
Protein Type
| Unknown |
Biological Properties |
General Function
| Involved in phosphotransferase activity, for other substituted phosphate groups |
Specific Function
| Catalyzes phosphatidylethanolamine biosynthesis from CDP-ethanolamine. It thereby plays a central role in the formation and maintenance of vesicular membranes. Involved in the formation of phosphatidylethanolamine via 'Kennedy' pathway.

Pathways
|
- Ether lipid metabolism
- Glycerophospholipid metabolism
- phosphatidylethanolamine biosynthesis
