Recombinant human ENPP7 (Ectonucleotide Pyrophosphatase/Phosphodiesterase 7), also known as sphingomyelin phosphodiesterase (SMpdase), is a membrane-associated enzyme primarily expressed in the intestinal tract. It hydrolyzes sphingomyelin, a key phospholipid in cell membranes, into ceramide and phosphocholine, playing vital roles in lipid metabolism, cell signaling, and gut barrier function. ENPP7 is notable for its substrate specificity, distinguishing it from other ENPP family members involved in nucleotide metabolism. Its activity influences intestinal lipid absorption, microbial interactions, and inflammatory responses, linking it to conditions like metabolic disorders, inflammatory bowel disease, and colorectal cancer.
The recombinant form of ENPP7 is produced using biotechnological systems (e.g., mammalian or insect cell lines) to enable controlled study of its structure and function. Researchers utilize it to investigate enzymatic mechanisms, develop diagnostic assays, and explore therapeutic strategies targeting lipid-related pathologies. Structural studies reveal conserved catalytic domains and metal ion-dependent hydrolysis mechanisms, aiding drug design. Recombinant ENPP7 also serves as a tool to study ceramide-mediated pathways, which regulate apoptosis, cell proliferation, and pathogen defense. Despite progress, its tissue-specific regulation and systemic effects remain areas of active research, emphasizing its potential as a biomarker or therapeutic target in gastrointestinal and metabolic diseases.
