PCYT2 is an enzyme that catalyzes the formation of CDP-ethanolamine from CTP and phosphoethanolamine in the Kennedy pathway of phospholipid synthesis. Alternative splicing results in multiple transcript variants. Recombinant human PCYT2 protein, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography. Synonyms: Ethanolamine-phosphate cytidylyltransferase isoform 2, CTP:phosphoethanolamine cytidylyltransferase, ET, Ethanolamine-phosphate cytidylyltransferase, Phosphorylethanolamine transferase.
