The protein encoded by this gene is a glycoprotein secreted from the pancreas into the digestive tract and from the lactating mammary gland into human milk. The physiological role of this protein is in cholesterol and lipid-soluble vitamin ester hydrolysis and absorption. This encoded protein promotes large chylomicron production in the intestine. Also its presence in plasma suggests its interactions with cholesterol and oxidized lipoproteins to modulate the progression of atherosclerosis. In pancreatic tumoral cells, this encoded protein is thought to be sequestrated within the Golgi compartment and is probably not secreted. This gene contains a variable number of tandem repeat (VNTR) polymorphism in the coding region that may influence the function of the encoded protein. [provided by RefSeq, Jul 2008]

Carboxyl Ester Lipase

Catalyzes the hydrolysis of a wide range of substrates including cholesteryl esters, phospholipids, lysophospholipids, di- and tri-acylglycerols, and fatty acid esters of hydroxy fatty acids (FAHFAs) (PubMed:8471055, PubMed:27509211, PubMed:10220579, PubMed:27650499).
Preferentially hydrolyzes FAHFAs with the ester bond further away from the carboxylate. Unsaturated FAHFAs are hydrolyzed more quickly than saturated FAHFAs (By similarity).
Has an essential role in the complete digestion of dietary lipids and their intestinal absorption, along with the absorption of fat-soluble vitamins (PubMed:8471055, PubMed:27509211, PubMed:10220579, PubMed:27650499).

Maturity-onset diabetes of the young 8 with exocrine dysfunction (MODY8): The disease is caused by variants affecting the gene represented in this entry. Single base deletions in the VNTR-region, that result in frame shift and protein truncation, have been identified as disease causing variants in MODY8 families (PubMed:16369531). An autosomal dominant form of diabetes characterized by a primary defect in insulin secretion, exocrine pancreatic dysfunction, altered pancreatic morphology, recurrent abdominal pain, and fecal elastase deficiency. Disease onset is at less than 25 years of age.
