Pituitary adenylate cyclase-activating polypeptide (PACAP) is a 38-amino acid peptide of the secretin-vasoactive intestinal peptide (VIP) family.

|
PACAP and VIP interact with equal high affinity with a common receptor and with low affinity with the secretin receptor.

The abilities of human and rat growth hormone-releasing factors (hGHRF, rGHRF), peptide histidine isoleucine or methionine (PHI, PHM) and the Gila monster venom peptides (helospectin I, helospectin II, and helodermin) to interact with guinea pig pancreatic acini were characterized and compared with vasoactive intestinal peptide (VIP) and secretin.

Each peptide inhibited 125I-labeled secretin binding with the potencies: secretin greater than helospectin I = helospectin II = helodermin greater than rGHRF = PHI = VIP greater than PHM greater than hGHRF.

|
VIP or rGHRF and PHI or PHM demonstrated high and low selectivity, respectively, for VIP receptors, secretin high selectivity for the secretin receptor, and helospectin I or II and helodermin a relatively high affinity for both VIP and secretin receptors.

A comparison of the genomic structure with other related receptor genes indicates that the exon/intron organization is well-conserved among the VIP/ glucagon/secretin receptor family.

Additionally, SCTR(-/-) mice were shown to have reduced renal expression of AQP2 and AQP4, as well as altered glomerular and tubular morphology, suggesting possible disturbances in the filtration and/or water reabsorption process in these animals.

|
By using SCTR(-/-) mice as controls and comparing them with wild-type animals, we performed both in vivo and in vitro studies that demonstrated a role for secretin in stimulating (i) AQP2 translocation from intracellular vesicles to the plasma membrane in renal medullary tubules and (ii) expression of this water channel under hyperosmotic conditions.

Agonist drugs targeting the glucagon-like peptide-1 (GLP1) receptor represent important additions to the clinical management of patients with diabetes mellitus.

|
In the current report, we have explored whether the recently described concept of a receptor-active endogenous agonist sequence within the amino terminus of the secretin receptor may also be applicable to the GLP1 receptor.
|
13 |

|
Indeed, the region of the GLP1 receptor analogous to that containing the active WDN within the secretin receptor was found to possess full agonist activity at the GLP1 receptor.
|
14 |

|
This directly supports the relevance of the endogenous agonist concept to the GLP1 receptor and provides new insights into the rational development and refinement of new types of drugs activating this important receptor.

Beside the large family A (rhodopsin-like receptors) and family C GPCR (metabotropic glutamate receptors), the small family B1 GPCR (secretin-like receptors) includes important receptors such as vasoactive intestinal peptide receptors (VPAC), pituitary adenylyl cyclase activating peptide receptor (PAC1R), secretin receptor (SECR), growth hormone releasing factor receptor (GRFR), glucagon receptor (GCGR), glucagon like-peptide 1 and 2 receptors (GLPR), gastric inhibitory peptide receptor (GIPR), parathyroid hormone receptors (PTHR), calcitonin receptors (CTR) and corticotropin-releasing factor receptors (CRFR).

In contrast to the larger and more thoroughly studied GPCR subfamilies A and C, the B1 subfamily is small and comprises only 15 members, including, e.g., the secretin receptor, the glucagon receptor, and the receptors for parathyroid hormone (PTHR1 and PTHR2).
