Description

Biochem/physiol Actions

Hemopressin is an endogenous hypotensive nonapeptide derived from hemoglobin. Hemopressin reduces appetite, acting as a cannabinoid CB1 inverse agonist. It blocks signaling by CB(1) receptors but not by other members of family A G protein-coupled receptors (including the closely related CB(2) receptors.
