Primary structure and tissue distribution of guinea pig gastrin-releasing peptide.
The primary structure of gastrin-releasing peptide from the guinea pig stomach has been determined by automated Edman degradation and shown to be identical to porcine gastrin-releasing peptide. Extracts of guinea pig brain and small intestine contained both gastrin-releasing peptide and its COOH-terminal decapeptide (neuromedin C) but the stomach extracts contained only gastrin-releasing peptide. Within the small intestine, highest concentrations of gastrin-releasing peptide-like immunoreactivity were found in extracts of the circular and longitudinal smooth muscle layers.
