Q7ZYQ3 Choline/ethanolaminephosphotransferase cept1 8355 None SL-0178 SL-0182 Endoplasmic reticulum membrane {ECO:0000250|UniProtKB:Q9Y6K0}; Multi-pass membrane protein {ECO:0000250|UniProtKB:Q9Y6K0}. Nucleus membrane {ECO:0000250|UniProtKB:Q9Y6K0}; Multi-pass membrane protein {ECO:0000250|UniProtKB:Q9Y6K0}. UNIPROT Q7ZYQ3 Pfam PF01066 PROSITE PS00379 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. {ECO:0000250|UniProtKB:Q9Y6K0}.
