Summary
This gene encodes a selenoprotein, which contains a selenocysteine (Sec) residue at its active site. The selenocysteine is encoded by the UGA codon that normally signals translation termination. The 3' UTR of selenoprotein genes have a common stem-loop structure, the sec insertion sequence (SECIS), that is necessary for the recognition of UGA as a Sec codon rather than as a stop signal.

Comments
| Comment Type | Description |
|---|---|
| Biophysicochemical Properties | Kinetic parameters: KM=1.8 uM for CDP-ethanolamine ; Vmax=76.3 pmol/min/mg enzyme with CDP-ethanolamine as substrate ; |
| Catalytic Activity | CDP-ethanolamine + 1,2-diacyl-sn-glycerol = CMP + a phosphatidylethanolamine |
| Cofactor | Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence= ; Name=Mn(2+); Xref=ChEBI:CHEBI:29035; Evidence= ; |
| 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. |
| Pathway | Phospholipid metabolism; phosphatidylethanolamine biosynthesis; phosphatidylethanolamine from ethanolamine: step 3/3. |
| Sequence Caution | Sequence=BAB21815.1; Type=Erroneous termination; Positions=387; Note=Translated as Sec.; Evidence= ; |
| Similarity | Belongs to the CDP-alcohol phosphatidyltransferase class-I family |
| Subcellular Location | Membrane ; Multi-pass membrane protein |
| Tissue Specificity | Widely expressed. Abundant in brain, placenta, liver and pancreas, followed by heart, skeletal muscle, lung and kidney. In brain it is strongly expressed in cerebellum, followed by the occipital pole and the frontal lobe |
