General description

The gene colipase (CLPS) encodes a lipolytic enzyme that is majorly expressed in the exocrine pancreas. This protein is also found in the stomach and intestine. Its structure includes 17 amino acid signal peptides and a five amino acid pro-piece at the N-terminus.

Application

Colipase from porcine pancreas has been used:

  • in the enzyme solution for lipase assay
  • in an enzyme mixture to simulate gastrointestinal digestion
  • as one of the apparent critical factors to study its effect on lycopene in vitro accessibility

Biochem/physiol Actions

Colipase is involved in lipid metabolism and apoptosis signaling. It is crucial for fat digestion. It is a pancreatic protein that prevents the denaturation of lipase and enables its attachment to the lipid-water interphase of the droplet. Colipase makes lipase accessible to the inner core of triacylglycerol. Defective colipase secretion induced by an insufficient exocrine pancreatic function minimizes the luminal hydrolysis of dietary fat. Lack of congenital lipase or colipase causes pancreatic fat malabsorption.

Features and Benefits

  • Overcomes the inhibition of lipase by bile salts.
  • Activity can be demonstrated turbidimetrically in an emulsion of triolein and sodium deoxycholate together with porcine pancreatic lipase.

Preparation Note

Dissolves in water to form a clear, colorless to faint yellow colored solution at 1.9-2.1 mg/mL concentration.

Colipase, like other pancreatic proteins, is liberated into the circulation in acute pancreatitis. Its concentration was measured in serum by a turbidimetric and in urine by a titrimetric method. The principle of both assays is based on the reactivation of

Colipase is a small protein cofactor needed by pancreatic lipase for the efficient dietary lipid hydrolysis. It binds to the C-terminal, non-catalytic domain of lipase, thereby stabilising an active conformation and considerably increasing the overall hydrophobic binding site. Structural studies
