Description

Amino Acid Sequence

D-Phe-Cys-Tyr-D-Trp-Arg-Thr-Pen-Thr-NH2

Application

CTAP has been used as a μ-opioid receptor (MOR) antagonist:

• to study the anti-hyperalgesic effect of dipeptidyl peptidase 4 (DPP4) inhibitor isoleucine-proline-isoleucine (IPI) and vildagliptin in carrageenan-induced inflammation
• to study the role of MOR in glutamate and gamma-aminobutyric acid (GABA) efflux during predator stress in rats
• to determine the endogenous opioid peptide involved in blocking pain induced by activated gastrin-releasing peptide (Grp⁺) neurons

Biochem/physiol Actions

CTAP is a peptide antagonist produced from somatostatin analogs.
