背景信息

**Background of PCYT2 Recombinant Protein**

PCYT2 (Phosphate Cytidylyltransferase 2) is a key enzyme encoded by the *PCYT2* gene, belonging to the CTP:phosphocholine cytidylyltransferase family. It catalyzes the rate-limiting step in the biosynthesis of phosphatidylcholine (PC), a major phospholipid essential for cell membrane structure, signaling, and lipid metabolism. Specifically, PCYT2 transfers a cytidine monophosphate (CMP) group from CTP to phosphoethanolamine, generating CDP-ethanolamine, a precursor for phosphatidylethanolamine (PE) synthesis. This reaction links nucleotide metabolism with glycerophospholipid homeostasis, critical for cellular integrity and organelle function.

Recombinant PCYT2 protein is produced via heterologous expression systems (e.g., *E. coli* or mammalian cells) to study its enzymatic activity, structural features, and regulatory mechanisms. Its recombinant form enables researchers to investigate post-translational modifications, substrate specificity, and interactions with lipid membranes or regulatory proteins. Dysregulation of PCYT2 is implicated in metabolic disorders, neurodegenerative diseases, and cancer, as altered phospholipid balance disrupts membrane dynamics and signaling pathways. For example, reduced PCYT2 activity correlates with hepatic steatosis and insulin resistance, while overexpression is observed in certain tumors.

Studies using recombinant PCYT2 have advanced drug discovery efforts targeting lipid metabolism. Inhibitors or activators of PCYT2 could modulate phospholipid levels, offering therapeutic potential for metabolic syndromes or neurological conditions. Structural analyses of the recombinant protein, including X-ray crystallography or cryo-EM, provide insights into its catalytic domain and allosteric regulation. Overall, PCYT2 recombinant protein serves as a vital tool for unraveling its biological roles and translational applications in human health and disease.
