**Background of LIPC Recombinant Protein**
Lipase C, hepatic type (LIPC), also known as hepatic lipase, is a key enzyme encoded by the *LIPC* gene, primarily synthesized in the liver. It plays a critical role in lipid metabolism by hydrolyzing triglycerides and phospholipids in circulating lipoproteins, particularly high-density lipoproteins (HDL) and intermediate-density lipoproteins (IDL). This enzyme facilitates the remodeling of lipoproteins, influencing their uptake and clearance, thereby regulating plasma lipid levels. LIPC’s activity is closely associated with cardiovascular health, as dysregulation contributes to atherosclerosis and metabolic disorders.
Recombinant LIPC protein is produced using biotechnological methods, such as expression in mammalian cell lines (e.g., HEK293 or CHO cells) or microbial systems, followed by purification to ensure high specificity and activity. Its recombinant form retains the native enzyme’s functional domains, including the catalytic triad (Ser-149. Asp-173. His-257) and heparin-binding regions critical for interaction with lipoprotein substrates. Researchers utilize recombinant LIPC to study its enzymatic mechanisms, structure-function relationships, and role in diseases like dyslipidemia.
Additionally, this protein serves as a tool for drug discovery, enabling the screening of inhibitors or activators targeting lipid metabolism pathways. Its application extends to diagnostic assays for evaluating hepatic lipase deficiencies linked to genetic mutations. By providing a standardized and scalable source of functional LIPC, recombinant technology advances both basic research and therapeutic development in cardiometabolic diseases. Studies continue to explore its interplay with other lipases and potential as a biomarker or therapeutic target.
