Pancreatic lipase-related protein 2 (PNLIPRP2) is a member of the pancreatic lipase gene family, primarily expressed in the pancreas and involved in lipid metabolism. Unlike classical pancreatic lipase (PNLIP), which hydrolyzes dietary triglycerides, PNLIPRP2 exhibits distinct functional characteristics. It lacks detectable lipase activity under physiological conditions but can inhibit other lipases, suggesting a regulatory role in fat digestion. Structurally, it shares a conserved catalytic triad (Ser-153. Asp-177. His-264) and lid domain with other lipases, yet its unique N-terminal domain may contribute to its inhibitory properties.
Recombinant PNLIPRP2 is produced using expression systems like E. coli or mammalian cells, enabling studies of its structure-function relationships. Its production often involves affinity tags (e.g., His-tag) for purification. Research highlights its interaction with colipase, a co-factor for PNLIP, where PNLIPRP2 competes with PNLIP for colipase binding, potentially modulating lipolytic activity. This mechanism has implications for understanding nutrient absorption disorders and metabolic diseases.
Clinically, altered PNLIPRP2 levels have been observed in chronic pancreatitis and pancreatic cancer, suggesting diagnostic or prognostic utility. Its recombinant form serves as a tool to investigate enzyme inhibition strategies for obesity treatment or to develop assays detecting pancreatic dysfunction. Despite progress, questions remain about its physiological triggers, tissue-specific roles beyond the pancreas, and potential therapeutic applications. Ongoing studies aim to elucidate its interactions with lipid substrates and regulatory pathways, bridging gaps in understanding pancreatic exocrine function and metabolic regulation.
