General rule information [?]

Accession PRU00674

Data class Domain
Predictors PROSITE; PS51342; COLIPASE_2
Name Colipase family
Function Colipase is a small protein of ~100 amino acids that functions as a cofactor for pancreatic lipase. It also binds to the bile-salt covered triacylglycerol interface thus allowing the enzyme to anchor itself to the water-lipid interface. Colipases contain ten cysteines involved in five disulfide bonds.

Comments [?]

case <FTGroup:1>
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.
Subunit Forms a 1:1 stoichiometric complex with pancreatic lipase.
Subcellular location Secreted.
end case

Similarity Belongs to the colipase family.
