Summary

CLPS (colipase, HGNC:2085) is a protein-coding gene on chromosome 6p21.31, encoding Colipase (P04118). Colipase is a cofactor of pancreatic lipase.

The protein encoded by this gene is a cofactor needed by pancreatic lipase for efficient dietary lipid hydrolysis. It binds to the C-terminal, non-catalytic domain of lipase, thereby stabilizing an active conformation and considerably increasing the overall hydrophobic binding site. The gene product allows lipase to anchor noncovalently to the surface of lipid micelles, counteracting the destabilizing influence of intestinal bile salts. This cofactor is only expressed in pancreatic acinar cells, suggesting regulation of expression by tissue-specific elements. Three transcript variants encoding different isoforms have been found for this gene.

  • Our findings demonstrate that the Arg92Cys polymorphism decreases the function of Cys92 colipase. This change may contribute to the development of type 2 diabetes. (PMID:17715423)

Function. Colipase is a cofactor of pancreatic lipase. It allows the lipase to anchor itself to the lipid-water interface. Without colipase the enzyme is washed off by bile salts, which have an inhibitory effect on the lipase. Enterostatin has a biological activity as a satiety signal.

Subunit / interactions. Forms a 1:1 stoichiometric complex with pancreatic lipase.

Subcellular location. Secreted.

Tissue specificity. Expressed by the pancreas.

Polymorphism. Variant Cys-109 is statistically significantly associated with an increased risk of type 2 diabetes.

Similarity. Belongs to the colipase family.
