CC   -!- FUNCTION: Colipase is a cofactor of pancreatic lipase. It allows the
CC       lipase to anchor itself to the lipid-water interface. Without colipase
CC       the enzyme is washed off by bile salts, which have an inhibitory effect
CC       on the lipase.
CC   -!- FUNCTION: Enterostatin has a biological activity as a satiety signal.
CC   -!- SUBUNIT: Forms a 1:1 stoichiometric complex with pancreatic lipase.
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- TISSUE SPECIFICITY: Expressed by the pancreas.
CC   -!- SIMILARITY: Belongs to the colipase family. {ECO:0000255|PROSITE-
CC       ProRule:PRU00674}.
