Propeptide: MNSGVCLCVLMAVLAAGALTQPVPPADPAGSGLQRAEEAPRRQLRVSQRTDGESRAHLGALLARYIQQARKAPSGRMSIVKNLQNLDPSHRISDRDYMGWMDFGRRSAEEYEYPS
Signal peptide: MNSGVCLCVLMAVLAAGALT
Modification: T52 Sulfotyrosine;T58 Phenylalanine amide
Glycosylation: NA
Mutagenesis: 52-52Y->F: Reduces the quantity of secreted CCK8 by 50%.

Function: This peptide hormone induces gall bladder contraction and the release of pancreatic enzymes in the gut.Binding to CCK-A receptors stimulates amylase release from the pancreas, binding to CCK-B receptors stimulates gastric acid secretion.
