Protein attributes

Sequence length	115 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	This peptide hormone induces gall bladder contraction and the release of pancreatic enzymes in the gut. Its function in the brain is not clear. Binding to CCK-A receptors stimulates amylase release from the pancreas, binding to CCK-B receptors stimulates gastric acid secretion.
Subunit structure	Binds to CCK-A receptors in the pancreas and CCK-B receptors in the brain By similarity.
Subcellular location	Secreted.
Post-translational modification	The precursor is cleaved by proteases to produce a number of active cholecystokinins.
Sequence similarities	Belongs to the gastrin/cholecystokinin family.
