Chromatographic characterization of gastrin/cholecystokinin peptides in bovine and porcine pituitary.

abstract：:The UII and urotensin II-related peptide (URP) genes belong to the same superfamily as the somatostatin gene. It has been previously shown that somatostatin activates the UII-receptor (UTR). In contrast, the possible interaction between UII and URP and somatostatin receptors has remained scarcely analyzed. Herein, we ...
